An ignition interlock is/should not be something that you just blow into to start the car. I have a friend that is required to have one, and beleive me, it is an obtrusive as hell device. If it is too cold, you must warm it up before you can use it. If it is too warm, you must cool it down. When you are driving, it repeatedly asks you to blow. If it didn't do that, all you would have to do is blow once when sober and then just keep the motor running. Then at every bar you would find a parking lot full of idleing cars.
Anyway, in the USA aren't we innocent until proven guilty? Do I really have to prove to my CAR that I am fit to drive? What bac is the cut off? In the case of my friend it is .025. That's pretty low. We have plenty of laws and penalties that deal with the consequences of drunk driving already, we don't need to add another layer on top.
The devices can be made to work in various temperatures, or to be disabled if they can't.
They don't need to test while driving, IMO almost no one will 'leave the car idling at the bar'.
Yes, you're innocent until proven guilty. The device does not jail you, it's not punishment. Why can't you board an airplane without being checked for a gun? Aren't you innocent?
Yes, you have to prove to your car you're not drunk. The cutoff would presumably be .08 (for people not convicted of drunk driving), could be adjusted for states if needed.
Thousands of people killed annualy by drunk drivers, hundreds of thousands of drunk driving accidents, say you are wrong, we do need this.
