Oh, I'm not saying these "Red Flag DUI" laws are in any way useful. Unfortunately the reality is that nothing short of incarceration/seizure of vehicles will prevent someone who is determined to drive from driving. Yes, the law abiding won't drive on a suspended license. Yes, the law abiding won't drive without insurance. But they're not your problem, since they're also not the ones that are driving drunk!
Which is the exact same argument we make regarding so called "gun violence prevention". The law abiding, who are those that will be following whatever stupid regulations the leftists come up with, are not the ones out there committing the "gun violence".
I agree that actual enforcement of existing law, with consequences commensurate to the crime committed, on the other hand, will have a significant impact on both those problems.
It's hard to be a repeat drunk driving offender if you're serving a 10 year sentence for vehicular manslaughter (too light a sentence in my mind, but that's an example).
It's equally hard to be a repeat offender for a drive-by shooting if you're serving a 10 year sentence for being a felon in possession of a firearm from the *last* drive by you committed.
