Casey was fined by the NYPD as part of a recent bicyclist dragnet, getting dinged $50 for not riding in the bike lane. He tried to tell the cop that sometimes the bike lane isn’t safe but the officer wasn’t having any of it. So Casey made a video of what happens when you only ride in the bike lane, despite the numerous piles of construction equipment, taxis, and other obstacles, deliberately crashing his velocipede and eating asphalt. Hm, there seems to be a logic error somewhere here.
The first part is his encounter with the cop. The crashing starts at about a minute in.
