This kind of crap will continue until the spouse, child or relative of someone important gets killed by one of these idiot assholes. The best outcome if they continue until such an accident would be if they died and the innocent driver, pedestrian or bystander would suffer minor, if any, injuries.
If it were a spouse, child, or relative of mine that got killed or seriouly injured by such antics, they better hope they get arrested before I find out who and where they are.
