Use a car as your weapon.
Just to clarify, as I said in a comment, I'm not getting at car drivers as a whole. The comment was more on the way the law is applied rather than suggesting that all drivers are murderous maniacs. I'm surprised that somebody can get away so lightly with using a weapon to attack a random passer-by with a defence of mistaken identity. If the guy had shot a gun at the victim, but missed, I suspect the sentence would have been higher.
