The thing is, and this is applicable with all laws, make the sentences harsh. Take their car away for a year, right then and there. See how much of this still goes on. Same goes for other crimes, murder, mandatory life sentence, no parole. That's the 'key' to getting rid of this crap that toxifies the world.....
You wonder why there's little to no crime in other types of the world, why, because the sentences are extremely harsh.
