I guess, but there are plenty of ways besides 2 beers to be "mildly impaired" while driving. Half of the time when you think somebody is driving drunk they're on their cell phones. Kids bopping around, loud stereos blasting, garbage on the dashboard and in the back window, people who hang their handicap tags from their rear-view mirrors, driving drousy...
Frankly I think a person can be above .08 and be a lot more attentive than this other shit that goes on constantly.
