Obviously, not everyone can be above average. Exactly half of all drivers have to be in the bottom half when it comes to driving skills and safety.

Maybe, but the bottom half is not necessary drivers worse than average.
I do not know how you would calculate "average". But there are people on the road that could pull down the average a lot. So that more than 50 percent are better than average.
- adwn 6y agoIn colloquial speech, most people don't differentiate between "mean" and "median". My guess is that, in that kind of survey, the participants read or say "average" and implicitly mean "median" – and exactly 50 percent of drivers are better than the median, by definition.
- Dylan16807 6y agoThe problem with not differentiating clearly between mean and median, is that you look out at other drivers and calculate a mean, then you assume that the median is the same. With a sufficiently skewed distribution this will hugely inflate your numbers, even if you have a realistic perspective of your actual skill.
