When I was about 9 or 10 I was racing one of my neighborhood friends around the block and ran into a parked car. I just got back up and laughed it off, as I was not hurt. In 7500+ miles of cycling as an adult (actually, more miles than that, but I only started tracking my mileage in July 2009), I've not yet hit/been hit by a car. I have had a few close calls (mostly people going straight through an intersection cutting me off).
