Car commuters are quick to identify the turds of the cycling community—cyclists riding fixies without helmets as if daring gravity and cars alike to bitch-slap them, cyclists riding three abreast, slowly, to taunt traffic. Why not go meet all the nonturdish, responsible cyclists at the Seattle Bike Expo? Hell, become one: Buy a bike. Get your bike fitted by a professional. Figure out the gear you need to become a commuter. Join a cycling club. Buy some antichafe cream. Find good riding routes in your neighborhood. Make the city better.
