Is it time to start calling out bad cyclists?

This morning myself and just one other chap are in the ASL box on Tooley street waiting to cross tower bridge junction road east to west. There are approx 6-8 fellow cyclists in front of us beyond the line waiting for the green...

Tower bridge Road now crossed, I passed some of the cycle traffic in front when next up there is a girl on a racer in the middle of the road going quite slowly. People on the inside behind me so I decided to pass on the right. She glances over her right shoulder and sees me then looks ahead again, so I proceed to overtake.

A second later she's stood up and gracefully turning right across my path (a U turn, presumably to go north over tower bridge) forcing me to slam on the brakes and jump out the pedals. I could only utter the words 'What are you doing?' which was greeted by a slack jawed 'what' expression and look of surprise on her face. I then followed up with 'You can signal' by which point I realised she had headphones in so I just rolled past her went on my merry way.

Failed to notice a small gash on my knee (from kneeing my bars in emergency dismount) so by the time I got to work I had a foot long blood trail running down my leg.

Made me wish my username was nuwanda...

Oh, er yeah. That was me.
Sorry man, was kinda in a hurry to get to ASDA before they shut. Medium sized frozen chickens don't hang around forever you know.
