Why Driving is Stressful

 

Driving in traffic routinely involves events and incidents. Events are normal sequential maneuvers such as stopping for the light, changing lanes, or putting on the brakes. Incidents are frequent but unpredictable events. Some of these are dangerous and frightening, like near-misses, while others are merely annoying or depressing, like missing one's turn or being insulted by a motorist. Driving events and incidents are sources of psychological forces capable of producing powerful feelings and irrational thought sequences.  Driving is a highly dramatic activity that millions of people perform on a routine daily basis.  The drama stems from high risk and unpredictability.  Driving has two conflictual structural components--predictability and unpredictability.  Both are present all of the time.  Predictability, like maintaining steady speed in one's lane, creates safety, security, and escape from disaster.  Unpredictability, like impulsive lane changes without signaling, creates danger, stress, and crashes.  For many people driving is linked to the value of freedom of locomotion.  On the one hand they get into cars and drive off where they please, the very symbol of freedom and independence.  But on the other hand, as they are ready to take off into the open, they encounter restrictions and constrictions, preventing them from driving as they wish due to regulations and congestion.

 

The following list identifies 15 widely known conflictual aspects of driving that act as stressors.  These are emotional challenges that are common occasions for expressing hostility and aggressiveness on highways and streets.

 

1.      Immobility:  Most of the body during driving remains still and passive, not like walking where the entire body exerts effort and remains continuously active.  Tension tends to build up when the body is physically restricted and constricted.

 

2.      Constriction:  Motor vehicles are restricted to narrow bands of highway and street lanes.  In congested traffic, one's progress is inevitably going to be continuously blocked by numerous other cars.  Being thwarted from going forward when you expect to, arouses the emotion of restriction and constriction, and along with it, anxiety and the desire to escape from the constriction.  This anxiety and avoidance prompts drivers to perform risky or aggressive maneuvers that get them and others into trouble.

 

3.      Regulation:  Driving is a regulated activity, which means that government agencies and law enforcement officers get to tell drivers how fast to drive where, and how.  Cars and trucks have powerful engines capable of going faster than what is allowed--ever.  Drivers are punished for violating these regulations which they are responsible for knowing and obeying.  This imposition, though lawful and necessary, arouses a rebellious streak in many people, which then allows them to regularly disregard whatever regulations seem wrong to them at the time or in the mood they are in.

 

4.      Lack of control:  Traffic follows the laws that govern flow patterns like rivers, pipes, blood vessels, and streaming molecules.  In congested traffic, the flow depends on the available spaces around the cars, as can be ascertained from an aerial view such as a traffic helicopter, or from a bridge above the highway.  When one car slows down, hundreds of other cars behind run out of space and must tap their brakes to slow down or stop altogether, as in gridlock.  No matter how one drives, it's not possible to beat the traffic waves, whose cause or origin starts miles from where you are.  This lack of control over what happens is frustrating, stress producing, and tends to lead to venting one's anger on whoever is around--another driver, a passenger, a pedestrian, a construction worker, the government.

 

5.      Being put in danger:  Cars are loved by their owners and they are expensive to fix.  Even a scratch is stress producing because it reduces the car's value and is expensive to repair.  Congested traffic filled with impatient and aggressive drivers creates many hair raising close calls and hostile incidents within a few minutes of each other.  Physiological stress is thus produced, along with many negative emotions--fear, resentment, rage, helplessness, bad mood, and depression.

 

6.      Territoriality:  The symbolic portrayal of the car has tied it to individual freedom and self-esteem, promoting a mental attitude of defensiveness and territoriality.  Motorists consider the space inside the car as their castle and the space around the car as their territory.  The result is that they repeatedly feel insulted or invaded while they drive, lulling them into a hostile mental state, even to warlike postures and aggressive reactions to routine incidents that are suddenly perceived as skirmishes, battles, or duels between drivers.  For many motorists, driving has become a dreaded daily drudge, an emotional roller coaster difficult to contain and a source of danger and stress.

 

7.      Diversity:  There are about 200 million licensed drivers in North America today, and they represent a diversity of drivers who vary in experience, knowledge, ability, style, and purpose for being on the road.  These social differences reduce our sense of predictability because drivers with different ability and purpose don't behave according to the expected norms.  The peace and confidence of motorists is shaken by events that are unexpected, and driving becomes more complex, more emotionally challenging.  Diversity or plurality increases stress because it creates more unpredictability.

 

8.      Multi-tasking:  The increase in dashboard complexity and in-car activities like eating, talking on the phone, checking voice e-mail, challenge people's ability to remain alert and focused behind the wheel.  Drivers become more irritated at each other when their attention or alertness seems to be lacking due to multi-tasking behind the wheel.  Multi-tasking without adequate training increases stress by dividing attention and reducing alertness.

 

9.      Denying our mistakes:  Driving is typically done by automatic habits compiled over years, and this means that much of it is outside people's conscious awareness.  Typically drivers tend to exaggerate their own "excellence," overlooking their many mistakes.  When passengers complain or, when other drivers are endangered by these mistakes, there is a strong tendency to deny the mistakes and to see complaints as unwarranted.  This denial allows drivers to feel self-righteous and indignant at others, enough to want to punish and retaliate, adding to the general hostility and stress level on highways.

 

10.  Cynicism:  Many people have learned to drive under the supervision of parents and teachers who are critical and judgmental.  We don’t just learn to manipulate the vehicle; we also acquire an over-critical mental attitude towards it.  As children we're exposed to this constant judgmental behavior of our parents who drive us around.  It's also reinforced in movies portraying drivers behaving badly.  This culture of mutual cynicism among motorists promotes an active and negative emotional life behind the wheel.  Negative emotions are stress producing.

 

11.  Loss of objectivity:  Driving incidents are not neutral:  there is always someone who is considered to be at fault.  There is a natural tendency to want to attribute fault to others rather than to self.  This self-serving bias even influences the memory of what happened, slanting the guilt away from self and laying it on others.  Drivers lose objectivity and right judgment when a dispute comes up.  Subjectivity increases stress by strengthening the feeling that one has been wronged.

 

12.  Venting:  Part of our cultural heritage is the ability to vent anger by reciting all the details of another individual's objectionable behavior.  The nature of venting is such that it increases by its own logic until it breaks out into overt hostility and even physical violence.  It requires motivation and self-training to bring venting under control before it explodes into the open.  Until it's brought under conscious control, venting is felt as an energizing "rush" and promotes aggressiveness and violence.  Nevertheless, this seductive feeling is short-lived and is accompanied by a stream of anger-producing thoughts that impair our judgment and tempt us into rash and dangerous actions.  Repeated venting takes its toll on the immune system and acts as physiological stress with injurious effects on the cardio-vascular system (Williams and Williams, 1993).

 

13.  Unpredictability:  The street and highway create an environment of drama, danger, and uncertainty.  In addition heat, noise and smells act as physiological stress and aggravate feelings of frustration and resentment.  Competition, hostility, and rushing further intensify the negative emotions.  The driving environment has become tedious, brutish, and dangerous, difficult to adjust to on the emotional plane.

 

14.  Ambiguity:  Motorists don't have an accepted or official gestural communication language.  There is no easy way of saying "Oops, I'm sorry!" as we do in a bank line.  This allows for ambiguity to arise:  "Did he just flip me off or was that an apology?"  It would no doubt help if vehicles were equipped with an electronic display allowing drivers to flash pre-recorded messages.  Lack of clear communication between motorists creates ambiguity, which contributes to stress.

 

15.  Undertrained in emotional intelligence:  Traditionally, driver education was conceived as acquainting students with some general principles of safety, followed by a few hours of supervised hands-on experience behind the wheel, or on a driving simulator.  Developing sound judgment and emotional self-control were not part of the training, even though these goals were mentioned as essential.  Most drivers today are untrained or under-trained, in cognitive and affective skills.  Cognitive skills are good habits of thinking and judgment.  Affective skills are good habits of attitude and motivation.  Drivers thus lack the necessary coping abilities such as how to cool off when angered or frustrated, or how to cooperate with the traffic flow and not hinder it.  This lack of training in emotional intelligence (Goleman, 1995) creates high stress conditions for most drivers.

 

It is common to relate aggressiveness to social and environmental factors, in addition to individual personality factors.  For instance, congestion on highways and anonymity in cars interact with faulty attitudes and inadequate coping skills to produce aggressive traffic behavior under certain identifiable critical conditions.  These apparent triggering conditions are accidental because they are unpredictable, and involve symbolic meaning for the dignity or self-worth of the interactants who may later report having felt insulted or threatened.  It is part of popular psychology to call these provocative and dramatic conditions "triggers" as in, "It's not my fault. He provoked me.  It's his fault. He made me do it."  The trigger theory of anger serves to absolve the perpetrator from some or all of the responsibility for the aggression or violence.  Here the attackers see themselves as the victims through a self-serving speech act (Searle, 1969) by which they escape culpability and opprobrium.  It is common for road ragers to show no remorse for their assault and battery, seeing what they did as justified and deserved.

 

Road Rage and Aggressive Driving

 

For millions of people driving has become a health risk, an economic risk, and a daily hassle, if not tragedy.  The highway environment has turned hostile and dangerous.  Government regulation of traffic and transportation has vastly increased.  A dozen states have passed aggressive driving bills that change what was merely a ticket and a check, to a misdemeanor or a felony, with mandatory classes in how to manage your traffic emotions.  Law enforcement initiatives against aggressive drivers are called "aggressive initiatives" while federal agencies are promoting the use of integrated action between several forces, including helicopter support.  Society's war on aggressive driving appears to be accelerating in the media and on the World Wide Web where numerous activist groups promote citizen involvement in monitoring and reporting the license plates of aggressive drivers.  The appearance in this politicizing of aggressive driving is that aggressive drivers are a group of dangerous people like car thieves or bank robbers.  But my research on what drivers think and feel behind the wheel convinces me that aggressive driving is a cultural norm, not a deviant behavior.  We acquire these hostile driving norms in childhood as passengers and as adults, we practice the cultural habit and pass it on to our children.  Individual differences remain so that the frequency and modality of expressing hostility is conditioned by social factors--gender, education, age, personality style, demeanor, or conduct.  For instance, we would expect gender differences in driving aggressiveness to be consistent with cultural norms for violence in the family or workplace.  Some relevant findings from a Web survey of 2010 respondents in 1988 (James, 1998).  They were responding to itemized lists of driving behaviors often considered aggressive and illegal.  By checking an item, the respondent was making a confession or a self-witnessing report "I sometimes engage in this behavior."  By tabulating the results in terms of demographic variables, one can explore various cultural influences on specific forms of aggressive driving.

 

                                                                  MEN               WOMEN

making illegal turns                                18%                 12%

not signaling lane changes                      26%                 20%

following very close                              15%                 13%

going through red lights                          9%                  7%

swearing, name calling                           59%                 57%

speeding 15 to 25 mph                         46%                 32%

yelling at another driver                         34%                 31%

honking to protest                                 39%                 36%

revving engine to retaliate                      12%                 8%

making an insulting gesture                    28%                 20%

tailgating dangerously                            14%                 9%

shining bright lights to retaliate               25%                 13%

braking suddenly to punish                    35%                 29%

deliberately cutting off                           19%                 10%

using car to block the way                     21%                 13%

using car as weapon to attack               4%                   1%

chasing a car in hot pursuit                    15%                 4%

getting into a physical fight                      4%                  1%

 

For each of these aggressive driving behavior, more men report doing it than women.  The differences in percentage points are statistically significant for all items.  These results confirm what earlier surveys have found, that men drive more aggressively than women and manifest road rage symptoms more regularly.  However, popular surveys also show a growing number of women are engaging in aggressive driving behavior and are involved in a higher rate of non-fatal accidents than men (Woman Motorist, 1999).  The greater aggressiveness of men drivers and the increasing aggressiveness of women drivers are cultural trends reflecting an expanding permissiveness towards the expression of anger behind the wheel.  Some of the rise in women's aggressive driving is attributed to the increased presence of women in the workplace.  There are 88 million licensed women drivers in the U.S. today.  The proportion of women in the driver population rose from 43 percent  in 1963 to 50 percent in 1999.  More women are stuck in congested traffic, and more of the female gender experiences the stress and frustration men have endured for decades.  Additionally, women have more stops to make while they cart children to school, sports, and lessons, as well as driving to work, running errands, shopping and banking.  Women are forced to drive under time pressure during congestion.  As a result, auto insurance rates for young women are now closer to that of inexperienced young men, who are still being charged 185 percent above the base rate.

 

Health professionals generally attribute part of the increase in driving "pugnacity" to social factors such as swelling congestion, urbanization, dual-income families, workplace downsizing that increases crowding, family discord, job dissatisfaction, and physical illness.  The connection between stress and illness has long been established in medicine and new research shows that driving related stress is no different from life stress in the way it affects our health (APA Monitor, 1996).  The overt expression of anger and hostile behavior is normally "inhibited" or kept under wraps because we are directly or indirectly punished for it in various ways.  In the past decade, public schools have implemented conflict resolution or peer mediation programs designed to help children acquire the habit of resolving disagreements non-physically, non-violently (Goleman, 1995).  The key element of this civilized conduct is the skill of inhibiting the physical expression of anger or fear, so it doesn't come out in provocative or violent behavior.  When a neighbor encroaches upon your territory, normally you don't start shooting or suing.  You first find out what's going on, why, and what you can do about it peacefully and lawfully, such as talking it over or lodging a complaint.  This principle of non-aggressiveness has been thrown overboard by the culture of cynicism on highways.  As educators and change agents, we must find ways to restore it.

 

Perhaps the biggest cause of unsafe highways is people's unwillingness to scrutinize their own conduct, preferring to blame other drivers.  Surveys consistently show that most people have an inflated self-image of their motoring ability, rating the safety of their own driving as much better than the average motorist's.  For instance, two out of three drivers (67 percent) rate themselves almost perfect in excellence as a driver (9 or 10 on a 10-point scale), while the rest consider themselves above average (6 to 8).  Surveys typically show that 70 percent of drivers report being a victim of an aggressive driver, while only 30 percent admit to being aggressive drivers.  This suggests that most drivers overlook their own faults and overestimate their competence.  One way to examine this hypothesis is to compare the aggressiveness of the two-thirds majority of drivers who rate themselves as near perfect with the one-third minority that see themselves "above average, but with some room to improve."

 

The difference is dramatic!  The drivers who considered themselves near perfect in excellence with no room for improvement, also confess to significantly more aggressiveness than drivers who see themselves still improving.  This reveals the lack of objectivity in self-assessment shown by two out of three drivers.  Despite their self-confessed aggressiveness, they still insist on thinking of themselves as near perfect drivers with almost no room to improve.  This egocentric phenomenon can be seen in specific forms of aggressive behaviors.  For example, those who see themselves as near perfect drivers, admit to twice as much chasing of other cars compared to those who see themselves as less perfect.  The difference:  15 percent vs. 8 percent is statistically significant.  The fact is clear:  part of being an aggressive driver is to deny that you need to improve.  This is what I call resistance to change.

 

Why Prior Interventions Have Been Unsuccessful

in Reducing Dangerous Driver Behavior

 

In North America, cars have been mass produced for 103 years and there are now 177 million licensed drivers in the United States alone. Driving is the most dangerous activity for the majority of people in an industrialized society. Driving accidents have killed millions of people since 1900 and the number of deaths and injuries increase in proportion to the number of drivers and the total number of miles driven in an area or region. In North America, deaths and serious injuries from driving accidents were reduced as a result of these developments:

 

1.      more and better roads

thus, safer roads with better traction, visibility, and maintenance

2.      better designed cars

thus, cars equipped with better safety devices and crash proof designs that save lives—safety belt, air bag, child restraint car seat, shock absorption and controlled collapse, crash tests with dummies

3.      better medical emergency services and infrastructure on highways and streets

thus, more survivors after crashes

4.      better law enforcement

including, more personnel, use of electronic surveillance devices on highways and key intersections, new legislation to facilitate the conviction of guilty drivers, greater involvement of courts in remedial driver training for offenders

5.      mandated driver and safety education in schools

including graduated licensing and other special provisions for elderly and handicapped drivers

6.      more sophisticated transportation management systems

computer controlled traffic lights, traffic calming devices, re-routing schemes, HOV lanes, alternative transportation initiatives

7.      economic incentives for drivers who remain accident free

added insurance cost for accident prone drivers, increased incentives or insurance reductions for accident-free drivers, special benefits accruing to enrolling in refresher courses and other self-improvement activities

It’s important to note that despite these definite and significant improvements in the seven areas indicated, the rate of traffic deaths and injuries remains relatively constant when viewed over a long term perspective of years and decades. For instance, in the 1950s the annual fatality rate due to driving accidents was around 50,000 while in the 1990s it has been around 40,000. Yes, there is a reduction, but the curve has quickly leveled off and remains above 40,000 deaths and over 5 million injuries annually in the U.S. There seem to be two opposing forces operating.

 

On the one hand, the external environmental forces for greater safety (less risk):

The construction of more and better highways to accommodate the increasing numbers of drivers every year

The design of better and safer vehicles

A more efficient medical infrastructure to handle victims of crashes

Greater use of highway law enforcement and electronic surveillance as deterrents

 

And on the other hand, the internal individual forces for maintaining high risk (less safety):

The widespread acceptance of a competitive norm that values getting ahead of other drivers

The daily round schedule of time pressure and its mismanagement through rushing and disobeying traffic laws

The weakness of driver education programs so that most drivers have inadequate training in emotional self-control as drivers

The media portrayal of aggressive driving behaviors in a fun context

The psychological tendency to maintain a preferred level of risk, so that increased risks are taken when environmental improvements are introduced (also called "risk homeostasis", see Wilde, 1994; 1988)

 

Scientists and safety officials attribute this resistance to accident reduction to the attitude and behavior of drivers who tend to respond to safety improvements by driving more dangerously. It has been noted that a critical aspect of driving is the driver’s competence in balancing risk with safety. The risk in driving is largely under the control of the driver. The driver decides at every moment what risks to take and what to inhibit or avoid. Risk taking is a tendency that varies greatly between drivers as well as for the same driver at different times. Thus, if a road is made safer by straightening it, or by moving objects that interfere with visibility, drivers will compensate for the greater safety by driving faster on it—the so-called "risk homeostasis" phenomenon. The result is the maintenance of a constant subjective feeling of risk that is the normal habitual threshold for a particular driver. In such a driving environment, the rate of deaths or injuries tends to remain high, despite the safety improvements that are introduced.

 

The institutional or societal response to this stalemate between safety and risk tolerance, has been to increase enforcement activities by monitoring, ticketing, and jailing hundreds of thousands of drivers. Nevertheless, the number of deaths and injuries has remained nearly steady, year after year. Besides law enforcement, there has been an increase in litigation due to aggressive driving disputes between drivers, as well as more psychotherapy and counseling services, including anger management clinics and workshops, and community initiatives. Nevertheless, these remain scattered attempts, and have been unable to alter basic driving patterns.  As detailed in this chapter, socio-cultural methods need to be used to change the driving norms of an entire generation.

 

From Traffic Safety to Driving Psychology

 

Driver education and training continue to focus on imparting a minimum knowledge of safety principles and of vehicle operation and manipulation.  Courses and manuals generally include a brief section on "driver attitude" and "driver error" and this practice constitutes an acknowledgment that personality habits of the driver ought to be addressed in the instructional process.  My research efforts have addressed this behavioral component, and to allow specific recognition of this subject in driver education and training, I have proposed the phrase "driving psychology" to represent this new driver instruction area.  Driving psychology refers to the knowledge drivers need to cumulate throughout their career as driver--between six and seven decades for most people in North America.  This knowledge is thus focused on self-instructional methods as reflected by the new paradigm called "Lifelong Driver Self-Improvement Program" consisting of a K through 12 driving psychology curriculum followed by lifelong membership in a QDC (Quality Driving Circle) (James and Nahl, 2000).

 

Driving psychology is a behavioral engineering tool.  Research in driving psychology uses the self-witnessing approach, which is a method of generating objective data on oneself as a driver (James, 1996).  The driver operates in three separate but interacting behavioral areas known as affective, cognitive, and sensorimotor.  In other words, it takes the motive of a goal destination (affective domain) to keep the car moving, as well as a variety of related motives (affective) such as the desire (affective) to avoid a collision or the emotion of anger (affective) at another driver.  Besides this, it takes knowledge (cognitive domain) of vehicle operation and traffic regulations to get through, besides making judgments (cognitive) about what other motorists are likely to do or not to do.  And finally, it also takes the coordinated execution or performance (sensorimotor domain) of movements in appropriate response to the motive and the judgment.  These three behavioral domains jointly and interactively constitute driving or traffic behavior.  My proposal for Lifelong Driver Self-Improvement Training has the purpose of empowering drivers to take charge of their habit structures in these three behavioral areas.

 

The new driving psychology and the older traffic psychology represent distinct paradigms to the study of driver behavior, as was anticipated by the distinction between input-output relations and those involving internal states (Michon, 1985). Input-output models use taxonomies or inventories based on task analyses, as well as functional control models of a mechanistic nature. Internal state models use trait analyses of drivers and their motivational-cognitive context. Michon (1985, p. 490) considers the input-output models as "behavioral" while the internal states models are termed "psychological." However, driving psychology views the affective and cognitive areas as equally behavioral to the sensorimotor. Inventories of driver tasks have so far been based on external or public observation and description of driving performance (McKnight and Adams, 1970). The self-witnessing approach is a way of obtaining internal behavioral data, sometimes called "private data."

 

Driving psychology is the study of the social-psychological forces that act upon drivers in traffic. Situations are analyzed through external as well as internal methods of data gathering. For example, in one study the aggressiveness of drivers was measured in terms of observed rate of speed reduction, or the making of some hostile gesture at pedestrians in a marked crosswalk. It was found that aggressiveness of both men and women drivers was higher against men pedestrians than women pedestrians. This is an instance of the external analysis of driver behavior. In another study, drivers spoke their thoughts out loud into a tape recorder giving their perceptions and reactions to traffic events and incidents. It was found that the average trip from home and work is filled with many incidents that arouse feelings of hostility and thoughts of mental violence (James, 1987). This is an instance of the driver's internal behavior. An approach that involves both internal and external analyses consists of interviewing drivers about their driving, either "in depth" or on a questionnaire, and relating it to their self-witnessing records. One may also have observers independently make observations of drivers who are making self-witnessing tapes, which also allows the correlation or concurrence of external and internal data.

 

Personality and character are related to a driver's style of coping with traffic stress. Acts, thoughts, and feelings in driving interact in an integrated system. A driving trip typically involves the presence of a dominant motive such as the feeling of being in a rush, or the desire to outplay other drivers by getting ahead of them. The dominant motive (affective domain) is a character tendency that expresses itself in other settings as well. For example, a person may experience hostile thoughts (cognitive behavior) towards others wherever competition is at work, whether a bank line, a restaurant, or switching traffic lanes (sensorimotor domain). Data on the private world of drivers show that frustration begets anger, which leads to feelings of hostility that are elaborated in mental violence and ridicule, and finally acted out in aggressive behavior.  It is evident that the aggressive behavior is an outward consequence of an inner interplay between the negative feeling and its conscious justification or condoning.  This threefold aspect of driving behavior is at the center of driving psychology.

 

The topics of driving psychology often overlap with traffic psychology or applied psychology, but the method of generating the data are distinctive.  One example is the study of risk taking in driving (Wilde, 1994). Few traffic situations are without risk. Drivers are constantly involved with this risk. Incidents occur all the time and the threat involved is experienced as stress. Reduction of traffic stress is a major concern for both driving psychology and applied traffic psychology. In the old paradigm methods include extending traffic safety education to children, providing driver education for adolescents, and continuing driver education for adults through courses, legislation, and public media campaigns. Driving psychology adds a new major component to these methods, namely the idea that driver training is lifelong self-training, and that it involves training our emotional habits in traffic, our thinking habits behind the wheel, and our style or overt actions for which we are legally and socially responsible.

 

Driver Self-Witnessing

 

Educators and test makers have used the thinking out loud verbalizations of college students to study their problem solving abilities (Bloom, 1956). Meichenbaum and Goodman (1979) and Watson and Tharp (1985) have made use of silent verbalizations in the form of self-regulatory sentences that mediate and control the overt performance of students and clients in need of greater self-control of their behavior in many areas (Luria, 1961). Abelson (1981) has proposed script analysis as a method of reconstructing the cognitive activities that underlie routine behaviors such as ordering food in a restaurant.  Ericsson and Simon (1984) have described their extensive attempts in protocol analysis which involves the tape recording of a subject's thinking aloud routine while engaged in problem solving activity of specific tasks (e.g., solving a chess problem).  This work allowed Simon to create the first chess playing computer program by rendering each thinking sequence into a program line.  More recently, the MIT media lab is known to be creating computers that not only model human cognitive processes but affective as well (Picard, 1997). These research and clinical efforts represent significant advances in the scientific study of the private world of individuals. The self-witnessing technique I developed is an attempt to obtain reliable data on the ongoing events in the private world of drivers. This psychological aspect of driving has not received attention in the extensive literature of driving or auto safety. The method was also used in the analysis of self-witnessing reports written by students while engaged in doing library research or using Web search engines (Nahl, 1998; 1997; Nahl and James, 1996).

 

The self-witnessing method is readily meaningful to people since they are routinely expected in their daily lives as part of being ordinary humans or citizens, to be able to report on their own activities (What did you do?  Who was there? etc.) and mental focus (What did you think?  What did you feel? etc.).  Drivers readily discuss many aspects of their driving behavior, external and internal. For example, when people are asked to write an introduction about themselves as drivers, they spontaneously mention various aspects about themselves such as how long they have been driving; what kind of cars they can drive (gear shift or automatic); how driving affects everyday life (its costs, dangers, frustrations, stress); what images they project as a driver (power, status, lifestyle); whether they consider themselves to be a good or bad driver; how they react to common driving situations; how their mood changes as a result of driving episodes; how the traffic went on a particular trip; their driving record (traffic tickets, accidents, near misses); and some others. These are thus dimensions of discrimination along which drivers spontaneously monitor themselves, or have the conviction that they monitor themselves. These beliefs may be called the driver's self-image, or the reputation of oneself as a driver.  There is a lot of protective territoriality or face work defensiveness associated with these beliefs about oneself.

 

Interviews with drivers, or written self-assessment scales filled out by drivers, yield retrospective data in which the respondents' recollection of facts is mixed with their self-image as drivers. By contrast, self-witnessing reports yield data that are not retrospective but on-going or concurrent.  The driver behind the wheel speaks out loud into a recorder at the very moment that the emotions, thoughts, perceptions, and actions arise spontaneously and concurrently with the act of driving. Later analysis of the tape and transcript displays in concrete and visible terms, the overt expressions of feelings, thoughts, and perceptions that accompanied a particular driving episode.  This method does not claim to obtain a complete and accurate "online transaction log" of the driver's affective states and cognitive processes, but only a sample of these.  The adequacy of the sample needs to be evaluated theoretically and practically. The initial effort in driving psychology has been the attempt to develop a taxonomy of driving behavior so that there might be a theoretically justified classification system capable of listing driver behaviors in the three domains and at relative levels of attainment or development.

The Driver's Threefold Self--Affective, Cognitive, Sensorimotor

 

In its modern version, behaviorism is committed to a unified theory that tries to deal with external and internal aspects of the self (Staats, 1975; Mischel, 1991). For instance, the concept of personality is defined in terms of built-up repertoires of basic habits. These are actually skills and errors that can be modified through further learning. This acquisition process is going on in three distinct domains of the person's activity: affective, cognitive, and sensorimotor.  All skills at any level of expertise contain affective, cognitive, and sensorimotor features.  The following transcript segment from a driver's taped self-witnessing record illustrates the threefold nature of driving behavior.

 

"Oh, no, there's a police car coming up from behind. I hope he didn't see me driving fast. Besides, I'm not the only one who is driving fast. If he pulls me over to the side, he has to pull everyone else over too. I'll be so embarrassed if he pulls me over. Everyone will know that I was breaking the law."

 

Content analysis focuses on the "speech act" value of the components of verbalizations (Searle, 1969; Nahl, 1993). For instance, "Oh, no" marks an affective stricture or a perception of doom; and indexes an emotional flooding-out. "I hope" marks a religious affection or an idealized picture of reality. "Besides, I'm not the only one" bespeaks guilt and self-justification; it raises the specter of personal catastrophe expressed in "I'll be so embarrassed... Everyone will know..." A little later this subject displays affections of condemnation or disapproval when another car cut in front: "Careless and pushy drivers always do things like that." In another episode, this person expresses anxiety and fear: "I almost sideswiped a car which had been traveling in my blind spot. As I was turning back into the middle lane I was in a state of mild anxiety. Thinking about what could've happened made me scared." Thus, expressing fear in a driving incident or, showing disapproval of another driver, are instances of affective driving behavior.  An individual's internal dialog can be used as an index of the affective states and the cognitive processes that constitute the internal component of any outward behavior.

 

"I should cut down on how fast I'm driving and maintain the required speed limit. I'm in the middle lane and yet I'm driving like an aggressive person in the left lane. I could be increasing my chance of becoming a victim on the road. If the police pulls me over and gives me a ticket it's nobody else's fault but my own. I should follow the rules. I don't want others to get a bad impression of me and think that I'm a speed demon."

 

Reasoning about propriety is evident in "I should maintain the proper speed limit" and "I'm driving like an aggressive person" which also indicates self-evaluation ("aggressive"). Propriety as well as morality scales are involved in the driver's reasonings regarding the self-attribution of error. ("It's nobody else's fault but my own"), while the entry "I don't want others to get a bad impression of me" reveals this person's image management techniques.  In the following entry the driver seems to be overwhelmed with the reasoned consequences of his action:

 

"I'm thinking to myself I could have killed the guy back there. I'm so careless. He must be swearing at me and saying what an idiot I am. I could've smashed up my brother's car."

 

Note that this self-analysis includes imagining what the others are thinking, feeling, or saying ("He must be swearing...").  Witnessing and describing one's reasoning about a driving situation, or attributing an error to oneself, prov
