Actually, the article says “I’ve found that about 10% of drivers truly identify the speed limit sign and drive at or near that limit,”. That is what we were discussing here, not the 85/15 percentile thing. (Sorry I should have said 90% rather than 85%). Of course the article doesn't say what those other 90% are doing. I suspect they aren't all breaking the limit - probably some are going slower than the speed limit.
