I understand the physics thing as it relates to safe following distances and speeds (and perhaps safe driving on slopes). Not the history thing, though, and the "don't drink and drive" thing has been pretty well impounded into everyone's head (not that it stops them when they're drunk…). And who knows? The components could come in handy.

But as for physics, they could just give you a handy graph with the suggested following distance, taking into account speed, slope grade, and weather conditions.
