Is it time to start calling out bad cyclists?

And, indeed, exercise patience when necessary. Waiting is OK. You don't always have to filter, especially not with short queues. I appreciate that the queues at Stockwell are probably rather long, but patience is a much under-rated virtue when manoeuvring in traffic. It can often be the best strategy for defusing potential for conflict.

I'll often wait patiently a few cars back and roll past all the nodders who scooted to the very front, especially if you only have to slow down earlier rather than stop and can then use gaps in traffic to move up. Of course, my aura of awesome also helps my travel through spacetime.
