you treat the core problem to save lives apalmer
the core problem with DUI is exactly that we allow alcohol and cars to be sold and people to drive them, and there are millions who did it illegally every year. Now, we COULD place breathalizers in every car .... blow to start, but that's much an inconvenience to the law abiding people isn't it ?
what else can we do to stop drunk drivers? we could make cars that go no more than 25 mph ..... that way if drunks DID hit someone, it was drastically reduce killing someone. but again people don't want to give up their fast to save lives, do they ?
