Actually, the 10 is a nationally recognized driving system. Called Smith something something, I think. 10-15 years ago, they wanted to change the following distance, and couldn't, because it would violate copyright, or something like that.Somewhere there is an old geezer who used to work in the Ivory Tower who thought all this 5 & 10 stuff up and probably got a promotion for it. He expected everyone to memorize it all but today he can't even remember his own name.
