Is it time to start calling out bad cyclists?

Yeah, I keep turning that over in my head- it would have just turned into a shouting match though, the other chap was very confident that he was riding in an appropriate fashion, and would have taken anything I could have said as an attack- which in many ways it would have been.

Better, I think, if I'd just thrown him and his bike over the railing into the Thames.

It's worse that he rides off thinking it's fine not to stop when peds have the right of way. Fellow cyclists, I think, have a bigger effect than peds or motorists when calling 'one of our own'. I'd like to think that in those quiet moments afterwards you still think about your actions even though you may have verbally lashed out at the source.
