Cyclists are not solely to blame. There are several bad drivers out there as well, and unthoughtful pedestrians, too. I express frustration at all three groups equally. If everyone - cyclists, pedestrians, and motorists - would focus on following the rules of the road, everyone would have an easier, more relaxed commute. Cutting someone off, racing through a red light, speeding down Comm Ave, swerving around pedestrians on the sidewalk, walking in front of a driver who has a green light...none of these things will save you more than a few seconds of travel time. Why take the risk of hurting yourself or, worse yet, others? And, please quit swearing at each other. I doubt your mother would like to know that your last words were, "F-You." Courtesy, please! On a related note, how can the city of Boston require that cyclists ride on the road without also requiring them to wear helmets. Bizarre, no?!
