What about passing pedestrians? Yesterday in Pebble Beach, CA I saw how a cyclist shouted at a pedestrian who was about to cross a road. On a clearly marked pedestrian crossing. The cyclist startled the poor pedestrian and proceeded to ride quite fast in front of him. Looked really rude and obnoxious. On the other hand the cyclist was on a very expensive bike clad in the very best racing clothes. I guess he needed that PR on Strava badly.
