What an interesting interpretation; although my logical side supports the idea of dui laws (of course, limits of .08 - .05 are ludicrously low and verdictive, in my opinion), I see your point. No harm, no foul. As someone who had gunners who shifted for me, as a young and reckless lad, I always drove well or maybe I was just lucky; never got stopped or had an accident anyway. That said, I can see the reasoning for some sort of DUI laws (not the current laws where a small woman can't even have a single glass of wine with dinner!). p.s.: I fully support your last phrase, testing drivers randomly is a farce, legally and morally.
