I have one friend who will drink 10-15 beers 2-3 nights a week and drive a few hours later. Granted, he's a big guy, so he's never blackout drunk or anything, but they'll be times when he's stumbling around on the way to his car. The rest of us will drink moderately and drive (maybe 3 or 4 beers in a few hours), but we realize when we're too drunk and leave our cars or spend the night. Our friend ALWAYS drives home. We feel a little hypocritical calling him out, but do none the less. The problem is, he never listens. We'll explain how even though he's been doing this for the past year plus, his luck won't last forever and something bad will happen eventually, but he'll just ignore us and drive home anyways. We can't very well stop him from drinking or take the keys away from him, as he'll just go drink with different people instead. Any idea's on what to do? We're just hoping he gets a DUI before he hurts himself, or worse, someone else. Oh, and he's the type of guy who thinks he's the shit, is VERY stubborn, and in his mind, always right, which doesn't make things any easier.
