McCormick, Walkey and Green (1986) found similar results in their study, asking 178 participants to evaluate their position on eight different dimensions relating to driving skill (examples include the "dangerous-safe" dimension and the "considerate-inconsiderate" dimension). Only a small minority rated themselves as below average (the midpoint of the dimension scale) at any point, and when all eight dimensions were considered together it was found that almost 80% of participants had evaluated themselves as being above the average driver.
