When it turns into chest thumping about how everybody else is a horrible driver when it snows and I can go anywhere witha FWD car when the 4WDs are in the ditch, it's always fun to bring up the concept of illusory superiority and the Dunning-Kruger Effect.
In 1981, Ola Svensen surveyed a number of drivers, asking them to rate their own driving ability compared to the driving ability of others. In the United States, 93% of the drivers rated themselves as above average for skill and 88% ranked themselves as above average in safety.
The Dunning-Kruger Effect explains this as a cognitive bias that causes people to overestimate their own abilities and underestimate their deficiencies when comparing themselves to others.
In other words, everybody thinks they're an awesome driver in comparison to others, even if they're actually terrible at it.
