I'm sure you've all heard the phrase, "Driving is not a privilege, not a right," correct? Well, this dude definitely lost his privilege to drive (hopefully forever), and I'm damn glad. I'm also glad they took his car, and even more pleased that they are now using it for good. I don't mind paying taxes for that at all!
Also, if the cops can seize your weapon for doing something very dangerous and stupid with it (like shooting cans off a school fence at night or something), even if nobody was hurt, then why can't they seize your car if you were doing something incredibly stupid and dangerous with it (like going 92mph over the speed limit in a neighborhood where I'm SURE children reside)? He could have very easily killed someone, and I think the police were quite justified in doing what they did.
The fact that they rubbed it in his face only makes the story that much better
