Although drivers’ driving habits have been investigated using self-report methods, some studies have reported inconsistency between self-reported driving exposure and actual driving data. Data on self-reported and objective driving exposure were collected from 66 drivers aged 50–83 years. Agreement between these measures was 0.07 and 0.03 for distance driven per day and number of days driven per week, respectively. Factors related to agreement between the two measures investigated, and the odds ratios computed by a binomial logistic analysis for gender and some attitudes (confidence to driving, hesitation about driving, and car as self-expression) were higher than those for other variables. Scores on these variables did not differ significantly between under- and over-estimated self-reports. These findings suggest that the direction of inconsistency between self-reported and objective driving exposure might involve different and general personality traits. Further, self-reported driving exposure may be affected to monitoring experiences brought by attitudes about driving.
