Is it time to start calling out bad cyclists?

I managed to crash into the back of a car on Rotherhithe Roundabout today.

Taking it all a little too casually, I threaded in between gridlocked cars, and ended up taking out some old duffer's rear light cluster.

I had to flag him down to swap addresses. Part of me thinks I should have saved myself the hassle and the £60 dent in the pocket.

He thinks I'm going to pay for a replacement - Little does he know that I'm just going to kidnap his dog, and that I've been planning this whole venture for weeks.

I rode into the back of a Golf on LB a few months ago. It was my fault entirely, was too close to it and he had to make an emergency stop. I smashed his light cluster and my arm took out a rear passenger window. He didn't seem to notice...when I eventualy managed to flag him down he acted so suspiciously that in hindsight It was appeared probable that he had just nicked the car such was his unwillingness to hear my apology and offer to pay for the damage....
