One of my friends has that mentality and honestly I think it's beyond stupid. Even assuming you "recover" enough from their assault with a car, or can walk after you go down, say you pull and blow their head off. Yes, they just nearly killed you. But you did just kill them. Guess who's going to be bending for Bubba? Not the guy in the car. So instead of getting injured or shook up, now you're going in for murder. Is that worth it?
Bet ya a dollar it goes to court, the kid's parents get him a good lawyer, and he gets probation, or community service, or has to take driver ed classes. He'll never see a night in jail.
