Cyclists who inconvenience people in Denalis, BMW's and Mercedes by riding on their roads, and delaying their arrival at the traffic light.

How unfair.

Playing leap frog with buses.

You need to develop the habit of riding just outside the door zone. If it is aline of parked cars, stay out there the whole time. If is a lone parked car, shouldercheck, signal and then swing out early enough and far enough to be outside the door zone without having to risk being rear ended.

I never do that. If I can't stay ahead, I stay behind. Otherwise you are selfishly delaying all those bus passengers and repeatedly putting yourself at risk of being injured or killed each time the driver is forced to either brake for you or try to pass you to keep to his schedule, and cut back into the righthand lane in front of you to drop off or pick up pasengers.

Commuters who make fun of slow riders who wear spandex. They are on a bike. Isn't that what counts?

Waiting behind 2 cars at 4 way stops that sit and look at each other, then both go, then both stop and stare some more, then both go.....

We had a car on a group ride on a hilly/rolling road pull around us and then stop dead a quarter of the way up every hill so everyone had to stop and unclip and then restart on an uphill. Did this three or four times. I was a little pissed, but I guess it was kinda clever.
