..........
Witness statements given to police[not just mine]basically absolved either car driver from blame-they really didn't have a chance to miss him............
I did exactly the same as a teenager, although I was lucky that only one car hit me.

I was riding along past my mates house when he called out from his garden. I turned in the road without looking and got thrown in the air by a car that was right behind me. I didn't hear it, I didn't see it, all because I was in a world of my own, oblivious to anything around me.
I've highlighted the bit above as although I was not too badly injured, and there was no damage to his car, that man came around my parents house every evening after work for a week to check that I was ok.
It was completely my fault but it had made him feel physically sick to think what could have been. My parents told him that it was my fault but it had clearly really upset him, a knock on effect that youngsters don't consider.
