Why aren't those people getting on that bus?

To be specific, the driver has stopped just to the left of their clearly marked bus stop space. I commute daily on the 66, and this is a constant problem, in many cases (like this one) without even the excuse that they are blocked in some way from pulling up to the curb.

BTW, I have many times seen bicyclists pass buses that are stopped this far from the curb on the right, even as the buses are discharging passengers - a confluence of two evil and illegal behaviors. (Yes, yes, I know - it's LEEEGALLL for bicyclists to pass traffic on the right, apparently even when it's dangerous in every way to do so. This past Monday morning I watched a cyclist squeeze between my bus, stopped at a light, and the parked lane of cars, through a space so narrow he couldn't actually pedal the bike - he was touching both the bus and the car as he eked his way through. But is it legal for ANY vehicle of ANY kind to pass a streetcar or bus on the right while it's discharging and taking on passengers? I don't think so...)
