I enjoy an occasional group ride. I prefer them on back roads. I have never been a part of a group that doesn't work cooperatively with motor vehicle traffic. In each group ride where there are new members we held a brief at the beginning of the ride where we talked about negotiating traffic and control devices. The leader would say "slowing" so everyone knew what to expect. We bunched up at stops and moved through as a single unit rather than going one by one. We didn't always come to a complete stop. I don't do that in a car either. I want to be respected as a road user, so I treat others respectfully. I won't ride with group of jerks.
