Why a private view of driving favors the driver
A driver experiences the trip from the inside: choosing a speed, checking a blind spot, easing off the accelerator. Other motorists are visible mostly through what they do, not why they do it. That difference makes it easier to credit oneself for caution while interpreting another person’s abrupt move as carelessness.
Psychologists call this kind of favorable self-comparison the better-than-average effect. It is not necessarily deliberate boasting. People often judge themselves using qualities they value—being alert, patient, or considerate—and can recall moments that seem to demonstrate those qualities.
Driving offers weak feedback
Many ordinary trips end without incident, but that outcome does not reveal exactly how much skill produced it. A safe arrival may reflect good judgment, forgiving conditions, or simply the absence of a difficult situation. Drivers rarely get a clear score showing which decisions prevented danger and which were merely lucky.
Mistakes by others, meanwhile, can be conspicuous: a missed signal or a sudden lane change is easy to notice. The contrast is uneven. One’s own careful intentions are available as evidence; another driver’s intentions are not. And because “good driving” includes several qualities, people can emphasize the ones where they feel strongest when making a comparison.
Confidence can outpace calibration
This perception matters because confidence and accuracy are different things. A driver who sees themself as especially capable may be less inclined to question a familiar habit or allow for the possibility of error. In practice, safer judgment depends not on winning a comparison with other motorists, but on treating uncertainty as part of every trip: leaving room, watching for surprises, and assuming that even a careful person can miss something.
The irony is that the very uneventful drives people use as evidence of their skill may offer the least information about how they would handle a genuinely difficult one.
