The OP words his post to blame the cyclist for everything.
OPs front bumper hit the cyclist who had the ROW, yet OP says cyclist hit him.

Not my intent - I agree - I should have seen him. But I do note that we were BOTH moving at the time of impact. I would have stopped had I seen him, I make no doubt he would have also had he seen me. He had the right of way, so - yes - ultimately my fault.

My purpose of this post was to se if anyone else had experienced being on the bad side. As I noted above, I have been both hit - and a bad one at that - and this was my first time as a hitter - I felt terrible! However, I think I could have behaved better in that I might have pointed out to him that he was not doing all he could to make riding at night that much safer. Although I am not denying blame, I wish that somehow he might see that he could have done a lot to avoid the accident by making himself more visible; light clothing, front lamp, reflectors. It was wet and there were lots of lights all around, the reflectors would still have helped. In the event - if he continues riding dressed like he was, he is increasing the risk of another accident, possible hurt to himself, his family and the person on the other side of the collision.
