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."

The aero helmet weighs out the flappy tracksuit, it's practically like riding naked.
