I don't wear a helmet when I drive because when I'm driving I'm strapped inside a steel cage that does a very good job of protecting me in the case of a collision. I do wear a helmet when I'm on a bike, not because of nanny-state laws, but because many drivers drive in the manner of someone with the luxury of being complacent because they are strapped inside a steel cage that does a very good job of protecting them in the case of a collision.
