I realize the laws vary from state to state in the US, but over here, if you blow in the bag and you're over the limit, you don't get to get back in your car. You get a chauffer driven ride to the cop shop where they do a blood test and confirm you're over the limit. (unless they have the 'booze bus' set up, in which case they do it on the spot) After that, you get to go home and sleep it off. It is a very rare thing for someone not to be convicted of drink driving once the blood test shows they're over the limit. Going to court is simply a formality, and a way for you to find out what your punishment will be.

I don't have a problem with this law. If someone is over the limit, they shouldn't be behind the wheel. It's pretty simple and very easy to prove. If you're dumb enough to drive after drinking, you deserve what's coming to you.

eta: They now also conduct random drug testing on drivers here. The same rules apply.
