Mate, I've been the guy on the bike hitting the car (which pulled out on me). Trust me, they know the risk. Riding a bike is risky, thats why its fun. They are "failing to stay within a designated lane" when lanesplitting, or something, which is illegal. Got booked for it once. $60. If it was my fault pimpspec, I would feel absolutely terrible if i hit a bike. It if was their fault I would be annoyed that my car was damaged.
One guy almost took me out twice in 5 minutes. Looked me in the eyes the first time. Old bastard.
Thats why you should always check mirrors and blind spots before making a move, you never know what is going to be there. Mind you, the old bastard mentioned above actually just failed to give way to me, twice.
