I doubt how anybody can claim they're "driving safely" when the only observer is oneself and there is no baseline to compare against. This is about as statistically meaningful as people buying homeopathy stuff because they "know" it works.

At least homeopathy doesn't kill bystanders.



93% of drivers think they're a better than average driver.

While I know what you're getting at, it is possible to have X > 50% of a sample be better (or worse) than the average -- just being pedantic :)


Amazingly... (assuming normal distribution) more than half of them are probably correct.


Nobody can judge what speed is safe for road conditions?

A good driver can - even when that speed is actually lower than the posted speed limit.
