Thats a completely different thing. THIS is intended for REPEAT offenders. You can't be against it because of something that you think it MIGHT turn into.
Thats what this is all about. Do I think that this infringes upon some people rights, sure. I also think that drunk drivers take away other peoples #1 right, thier right to live.
It's one of those things that to protect MANY, a few will have to lose some rights. Don't drink and drive, don't lose any rights, it's simple.
