You've seen them (or maybe you are one): holier-than-thou urban bicyclist who think they're better than their environmentally destructive, car-driving brethren.
Will Doig of Slate's Dream City blog is a cyclist - and he has written about the image problem of urban bicyclist:
Urban bicyclists have an image problem. They’ve become stereotyped as pretentious, aloof jackasses, and a lot of this has to do with the changes taking place in cities right now. [...]
Railing against bikes, in fact, became a great way to sell papers. A hundred years ago, newspapers ginned up scare stories about the threat that hapless women on bicycles posed to pedestrians. Today, old-school tabloids like the New York Post have found that the bicyclists-versus-everyone narrative still resonates. In Op-Eds with titles like “Bike-Lane Bloodbath,” bicycles are portrayed as weaponized toys, and isolated accidents are held up as proof that bicycles are an urban menace. Last week in San Francisco, a 23-year-old bicyclist was charged with misdemeanor vehicular manslaughter for striking and killing a pedestrian — a tragic incident, but one that occurred in a city where 800 pedestrians are hit by cars every year. Still, the story was front-page news, sparking an online uproar: “I’m sick of bicycles and their cocky, self-righteous riders,” one commenter wrote on the San Francisco Chronicle’s website. “Bicyclists believe that they are untouchable.”
