Just to be clear, I don't block bike lanes unless there is a bus zone that I am servicing. We're trained to do that to keep cyclists from plowing into a passenger leaving the coach. (You'd be amazed at how many times I've seen that almost happen... Think: What happens when you see a bus pull over to a bus zone with nobody at the zone? Might that bus possibly be letting pedestrians off? Hmmmmmmm... )
If there is a bike lane and I'm at a red light I leave that open and just keep an eye out for cyclists so I know they are there. Yes, the same scenario I describe above can happen, cyclist planted in a blind spot, but at least there is more space for the cyclist so we should be able to happily coexist.
