Is it time to start calling out bad cyclists?

I was in the cycle lane on the eastern approach to the northern end of Blackfriars bridge last night, slowing for the red light/queueing traffic and cyclists in front of me when a dickhead undertakes me (in the fucking cycle lane, there's not much room for that) at speed (actual, balls-out (he did not have his balls out) speed). Why? Why would you do this?
He barrelled into the waiting crowd of commuters but didn't have the temerity to jump the red light. It was mystifying.

That could have been me... was it in the right hand lane which turns right into Victoria Embankment?
