I strongly disagree with the OP.
But then again, I lost an older brother to a drunk driver.
Driving impaired is driving impaired, be it at a .08 BAC, or .15 BAC - either is deadly to innocent persons in the path of the vehicle.
There's no Constitutional right given to strap on several thousand pounds of steel, rubber, and glass, then go kill somebody.
None. Go see if you can find it enumerated in there, or in the Amendments.
IOW, your Constitutional rights of Life, Liberty, and the Pursuit of Happiness end where mine begin.
If your happiness gets me killed, then it ain't a right.
Doesn't mean you can't drink.
Doesn't mean you can't drive.
It does mean, however, that you cannot drive impaired, and because everybody's body chemistry and tolerance to ETOH is different, they've set the BAC limit at .08 in most of the states.
I know, it's an arbitrary thing, and I'm sure the knee-jerk gun law analogy will be coming in this thread forthwith.
Regardless, some people think they can hold their liquor and get behind the wheel. If it weren't for them, we wouldn't be having this discussion now, would we? :|
