I am not excusing the behavior, but it is all too easy to get a chip on your shoulder about the bike lanes. An extremely common thing to see around here, which I have NEVER seen anyone ticketed for, ever, is to invent a parking space by pulling to the side of the road and having half the car on the sidewalk and the other half in the bike lane. In some instances this will even be on a stretch of sidewalk that is painted yellow. On my commute home it is rare, very rare, to not pass by at least one of these.

So, this particular instance was because the vehicle was broken down and the driver genuinely had no control over the situation. I don't know about the area of the country where this happened, but what are the odds that same group of cyclists had already passed one or two vehicles that were just parked in the bike lane prior to passing this particular woman? People get that chip on their shoulder when their space is routinely violated just for convenience.
