To the jackholes who zoom past pedestrians at break-neck speed nearly running them over: There is a reason the sidewalk is called a sideWALK, and not a sideRIDE - it was designed for people to WALK on it, not RIDE on it. If you are too much of a wimp to brave the traffic, that is perfectly understandable. Simply find streets that with fewer cars on them, and bike there. I don't care how hip it is to 'bricolage' (look it the fuck up if you don't know what it means); the sidewalk's intended function was/is for pedestrians and not for traffic, and when you are cyclist, you are traffic.
