It's appalling that so many of these cyclists seem to lack basic common sense and manners. One young woman once came careening around the corner and very nearly hit me as I walked past a convenience store. After she skidded and swerved she managed to stop, and seemed to be terrified when I started to shout at her in English using a few expletives.
Even if these people are entirely selfish, don't they fear for their own safety? I almost never see any of them wearing helmets, and they often dart through pedestrian traffic.
