Is it time to start calling out bad cyclists?

It's the ones who actually wait at the edge of zebra crossings and then only cross when you stop that bug me.

If I see them, I'll slow down - aiming to hit the crossing well behind them/after they've crossed, yet still they stand there gaping until I'm 2 feet from them, despite a friendly nod to cross.

Why do they do this? Because other cunting cyclists won't stop.

Not just cyclists, either. in London it's 50-50 whether anyone will stop. I certainly never cross in front of a Volvo in Stamford Hill; the Hasidic types seem to think that the appropriate response to a ped on the zebra crossing ahead of them is to accelerate loudly and screech to a halt at the last possible moment only if you haven't leapt out of the way.
