Been hit twice by cars, one sideswipe (which didn't even knock me down) and one t-bone, neither my fault. Have ran into three cars, two t-bones (both partially my fault) and one sideswipe (completely my fault). All have been walkaways, albeit with a fair amount of bruising and road rash, and a few wheel and miscellaneous component replacements.

Factoring in single vehicle crashes (*snap* hey, where did my pedal go!? hmm, I used to be able to catwalk a bike when I was a kid, I wonder if I still can? oooh, I should take a shortcut through that empty lot that's overgrown with tall grass and fireweed that couldn't possibly be hiding any bike stopping obstacles! etc, etc..) I'm averaging about one wreck per year as an adult cyclist, although the first half dozen are all clustered up in my first two years of cycling. Now I just ride more slowly and defensively and only do something truly boneheaded once every few years.
