Just had my wing mirror clipped (and broken) 
It was a 30mph Road, and a parked car was blocking my side of the road. I went around the parked car as the road ahead was clear when I moved off, but then a man came speeding down and didn't stop for me despite seeing I was moving past a parked car - he wedged past and clipped my wing mirror on the way when I was moving back to my side of the road.
I stopped, and so did he and another guy who witnessed it. His mirror was fine, but said it was my fault as he had right of way. So we agreed to shake hands and leave it. The witness said the guy was speeding down the road and was at fault, and I should have pushed further in terms of insurance.
I have no idea how it all works, I've never been in an accident, but I didn't think going though insurance would be worth the excess and effect on no claims, especially if I was at fault. Just wanted to gather opinions on if I did the right thing to just let it go?
