Is it time to start calling out bad cyclists?

Also I giggled when a rider on a Brompton type bike pushed through a throng of riders who stopped at a red at the northern end of the Waterloo bridge (southbound lane) at around half 6 yesterday evening. The fella nearly jumped off his saddle (and his skin) when one of the massed riders shouted something to the effect of ''Oi! its red you Idiot''.

His clearly audible statement was greeted by a round of ''Well said mate'' by those of us on the northbound lane. But it does show proof of changing attitudes that what must have been at least 10 or more riders were patiently waiting for the lights to change rather than charging through like a herd of wheezing and creaking buffalo.

Very interesting. I just came here to say, I think Im out of the game. I upset this guy on Southwark Street last week. (he was a total bedwetter TBH). He did that thing of over shooting the stop lines and stopped exactly on the ped crossing and there wasn't a lot of space for crossing anyway. A few other cyclists turned up so I didn't wanna say anything then and waited until things spread out.
He just flipped out in no time screaming at me to fuck off and that I'd cause him to have an accident.
I didn't swear at him, threaten him, or belittle him. Just tried to engage in conversation. If that's the case then I'm out. I don't want anyone turned off cycling. But if anyone knows whom this guys is (Northern Irish, I think, with dark hair) apologise on my behalf. I was never looking to cause that amount of hurt to him but he does need a serious dose of HTFU.
