A New York Times article about the bike lane feud being waged by cyclists gives some insight into the trend of retaking the streets. There are several ways that cyclists are combating cars that infringe in the bike lanes. Pubic shame, tagging bike lanes with ant-car graffiti, and even fake parking tickets.
…some cyclists have handed out fake but realistic-looking summonses to drivers in bike lanes, leading at times to arguments. Others said they have slapped stickers on cars that look like those pasted on vehicles that fail to make way for the Sanitation Department street sweepers.
These are all great gorilla tactics, and will probably only stimulate the fringes of the bike movements (and polarize the fringes of the car culture). My opinion is that the best way to defend bike lanes is to have them full of bikers. It sounds obvious, but actually if there were so many bikers traveling in the bike lanes there would be no room for cars. In addition to gorilla anti-car tactics I’d like to see NYC fixed gear head and commuters try to grow in numbers to run cars off the streets.
