I hit an SUV the other day. It was my fault.

I was in an urban area and (foolishly) decided to pass a slow moving (stupid) driver on the right. He decided to suddenly turn in to a parking spot and I smacked the side his car as I was turning alongside him in to the spot. He heard the noise and stopped and I drove in front of him and rode off. I didn't actually hit him hard, it was only my arm / shoulder that bumped his car and I didn't do any damage.

There, a relevant story for this thread.
