Is it time to start calling out bad cyclists?

There's probably a bad pedestrians thread, but tonight I was walking my bicycle from the bike racks to the curb, not near anybody, and a passing guy tells me (seriously): "You should be on the road!".

Totally made me smile though, that made my evening.

Ha! had the same thing last week as I left my office in Wandsworth! Old Guy was really ranting at me. I had to turn round and calmly point out I'd just wheeled my bike out the gates of teh car park and was not about to push the frame into the oncoming-traffic-flow-of-death...

He was a bit stumped and just started screaming at a nearby nodder
