I know that after a while, I essentially rode a motorcycle with the attitude that a car couldn't hit me even if they were trying to. It is a lesson I try to apply to bicycling.
It's funny, I say the exact same thing to my wife. "They couldn't hit me if they were trying to - I refuse to let them".
I've also got to wonder at the crossover effects of being a safety-conscious cyclist. I think my car driving safety has improved immensely.
