Good post - this has struck me too. By the way, this is a good example showing that social life and human behaviour in general is much more "law-like" and indeed predictable than many "anti-positivists" in the social sciences would have it. Car drivers' behaviour is remarkably regular and predictable, even though it is, as you say, in no way trivial to drive a car.

Still many mistakes which end up causing accidents are made, and thus I'm sure automatized or semi-automatized cars could decrease the number of accidents hugely.
