"Stunt driving" should come with a lifetime driving ban.
If you were to point an unloaded, legally owned, gun at a single person you would not only get some serious charges but you would be banned from owning firearms. But driving a literal ton of steel at speeds that will pulp the body of anyone you hit, on public streets, is only a suspension.
Fuck that guy, and every other BMW/Audi/Merc weaving the 401 like they are playing GTA in their parent's basement.
