honestly, fuck these guys. If I don't feel like i want to edge down the side of a bus, HGV, car, truck, chicken, dinosaur, whatever at a set of lights or in live traffic deal with it. Different riders react differently under circumstances, last thing anyone wants is to feel pressure from other cyclists in situations that they SHOULD completely understand.
This. I'm perfectly happy to lose a couple of minutes waiting behind a large vehicle, rather than wasting my life under its wheels.
