Is it time to start calling out bad cyclists?

Not quite sure if this is worthy of "calling out" but the man/lady wearing the giro TT aero helmet, riding always in the drops - slowly - flappy tracksuit on, red and chrome langster, undertaking stationary people and proceeding through red lights and pedestrian filled intersections (from Rosebury ave to Holborn). I would have been tsk tsk ing furiously to myself if you hadn't looked so amusing while doing so. I just do not understand.

That is the world's most popular cycle route. There must be five million bikes go through each cycle of the lights at the bottom of Rosebery Avenue, Grays Inn Road, Clerkenwell Road double junction thingy. And then the lights change and its the death sprint into the pinch as the road narrows and a thousand cars, buses and lorries all try to beat the cyclists to the next red light one hundred metres down the road.
