It's called a slippery slope. That's why the NRA is so against *any* gun limits, even when they recognize there's really no reason for a hunter to own an assault rifle fed by a 200 round drum. Once you start making consessions, it's much easier to keep making them.
Regarding the breathalizer thing, I'm with Austin. I'll be damned if people that drink and drive like idiots are gonna require *me* to futz with a huffer every time I want to start my car. If that were law, the 1st thing I'd do to my car is disable it... and I'm sure that's what most people would do, so then they'll have to make it a felony to disable your own huffer, so now I'm a felon
. And what about all the other substances that impare your driving ability? Will that huffer detect marijuana, or will that be another device? Or what if I've got a cold and take NyQuil, now I can't drive my car.
The real solution is to educate people about driving. I think a high performance driving school type curriculum needs to be included in basic drivers training. Take those snot nosed kids, and spin them at 90mph on a wet skidpad. Scare some respect into them, and make them better drivers. Teach them to realize that cars aren't toys, and that if you're not totally in control, they will bite you in the ass. They'll think twice about getting behind the wheel after a few drinks. They'll also think twice about answering that cell phone or watching that DVD.
And if you really want to curb drink driving, how's this: you drink, you drive, you kill someone, it's murder 1. No invollentary manslaughter, no vehicular homicide. It's premeditated, cold blooded, murder, and you go away for life, or get the chair. Just a little insentive to stay sober behind the wheel. Americans are far too nonchalant when it comes to driving. You don't hear about endemics like ours in other counties... everywhere else driving is an expensive privlidge, here people think it's a right.
