There was one day last summer I heard the crunch of 2 fender-benders in one 5 km ride. Both were pretty much beside me. They could have been caused by pretty much anything, the visual distraction of myself included.

But if I stood around to give statements for every scratched bumper, I'd never get to work. I have been witness to a number of more serious accidents in which I stop to render aid, regardless of whether I'm driving or cycling (and in most cases I'm the only one that does) But it's (slightly)harder to get sued here than in other places.
