Is it time to start calling out bad cyclists?

I mean, I will enrage some drivers just by existing on a bicycle

I get your general point, but there's a key difference between you pissing off some goon just by taking primary and Snow going through a red.

As someone that cycles, then, what are my responsibilities towards you - another person that cycles

As you identified a couple of posts back, the original point is that Snow was president of the CTC. The only 'collective responsibility' is that towards any other road user - not to directly endanger them.

Personally I doubt anyone can claim the godlike perceptual skills to be absolutely sure that no-one else is going to appear out of nowhere if you go through an apparently deserted red, but that's a whole other (Bikeradar) argument.

Anyway - Snow, WAC, I hope he spends ages choosing bread, artisan cheese and pâte for a picnic and when he arrives at his chosen site finds he's forgotten to bring a knife, etc etc
