I live in one of the most bike-friendly cities in the US (according to Bicycling magazine). The behavior of bicyclists here, as far as riding safely and in a law-abiding manner, is _far worse_ than other cities I've lived in. Every day when walking down a sidewalk, I'm buzzed by one of these idiots riding by at high speed. I've seriously considered getting a "rear-view" mirror just to protect myself. Though I've cycled thousands of miles in prior years, I no longer do, partly because I don't want to be associated with such behavior.
