Unfortunately, someone could just as easily be drunk in their own homes and go driving in their car. What's needed is good drunk driving enforcement, not Gestapo-like tactics ruining the day for people who are just having a good time. I feel that as long as someone has a designated driver, they can have all the fun they want (as long as they aren't getting so drunk that they are causing real problems such as fights or are getting sick). Are they going to start busting wedding receptions or company Christmas parties now if they are held at a public restaurant? Give me a break
Yeah, well, where I grew up the cops had more important things to do than arrest people for being drunk. On a Friday night the town was thronged with drunk college students and other young folks. The general rule the cops used was "If you can get up and walk away, get a taxi, and go home, fine." Otherwise they'd haul you off to the drunk tank and/or hospital, which really didn't happen all that much. Idiots who broke glass in the streets, committed vandalism, hassled women or otherwise made a nuisance of themselves also got a free ride and overnight stay in the drunk tank.
I found in my drinking days tht it was almost impossible not to wind up in the car to get more beer, to get cigs, whatever... you always ran out of something. Prohibition NOW!
