You got one group of people screaming to get drunk drivers off the roads nearly to the point of wanting any blood alcohol content to be a felony DUI. Then you have everyone else who realizes that maybe we should really be targeting the ones who actually can't drive safely. Or instead of staking out a bar to catch people when they leave, the cop should sit at the door and offer free breathalyzer tests to anyone leaving. There is more, but dang that is a screwy issue.
Oh indeed. I don't support drunk driving but I've noticed over the years that those who get into serious 'drunk' accidents, IE fatal ones, are generally at multiple times the legal limit. IE lowering the limit to .08 from .10 probably didn't save many, if any, lives.
That being said:
Go after the 'super drunks' - seriously, they've actually created 'enhancements' in many states when you're way over the limit, because they've noticed that they're the ones in deadly accidents.
Give drunks in the back seat of their car asleep in the bar parking lot a night in the drunk tank, or even just a ride home. A ride home is a lot cheaper than convicting somebody, and helps build police trust. Giving them a dui, just incentivizes them to drive home because it's 'safer' to only be on the roads for a short time than in the lot for hours.
It should not be possible to get a dozen DUI convictions. At that point they've already lost their license for life, and are just flouting the law driving without a license, likely without insurance, etc...
