>The photo is a bit exaggerated, but to be fair most drivers go out of their way not to see any cyclists queued up when they want to make a turn through the bike lane.

Which suggests that having a queue there is probably not a good idea to begin with.

It would make more sense to have the cyclists in a bunch that can clear out quickly and then make vehicular turns possible.

The objection to having bikes in a bunch would be that cars can't pass them, but at busy hours passing cars only get momentarily ahead anyway - even with care to keep filtering past stopped traffic appropriately slow and careful, net progress on a bike can approach twice that of a car, so the few rounds of leapfrogging before the car is left permanently behind is only needless churn and repetition of a slight, but non-zero risk that can eventually add up to an incident.

Probably it would all be smoother if everything just moved at bike speed during busy hours, and passing bikes was something that drivers only tried to do at hours when the lights weren't causing car backups.
