I would say that was bad for bicyclists as a whole. Every person they cutoff, every person they scare will have a bad impression of bicylists. It is technically sort of kewl because as a lame fatguy in kansas i know i can't ride like that, but at the same time i know that riding like that in and out of traffic, between cars, the wrong way on a street, is not just dangerous it is statistically going to involve an accident if they pursuit it.
Did they have brakes on their bikes, were they fixed? One was for sure when he put his feet up, not sure about the other. What sort of camera? Me? I wouldn't do that stuff here because as i said im a fat middleaged guy and because we already have enough people here that just don't get the idea of a bicycle on the street.
So to answer the question both insane and crazy and also foolish.
