Hrm, depending on body weight and tollerance I see nothing wrong with a beer or two or a glass of wine and then driving.
I do agree though, that drinking and driving is a big problem and we should all do what we can to stop it.
Heh, any friends of mine that read on this forum should laugh remembering the time I decided to walk home quite a few miles in the rain cauz I didn't feel I was fit to drive
