When I first started randonneuring back in the late 70s (riding with the four guys who went on to become the first Canadians to ride PBP), we agreed to a strict policy: We were out on personal rides, and were expected to adhere to all of the standard rules of the road. This meant stopping at red lights and stop signs (well, pretending to stop at stop signs anyway, so at least slowing down enough that we could stop IMMEDIATELY if unseen traffic suddenly appeared). And if the red light we encountered at 2 in the morning didn't turn green, it was permissible to assume that it was not functioning for bicycles, so it was OK to run it if there was no other traffic. But at least we had stopped for it.
So it really annoys me when I see guys on brevets ignoring stop signs and running red lights. I'm glad they hand out time penalties at PBP for such infractions, and it would be nice to see the same penalties here. What I find particularly annoying is when you drop somebody, but they're able to catch back on because they have run the last few red lights and stop signs. I guess I'm just too competitive and antisocial. If they are able to recover and catch up by their own effort, that's different, and it's commendable. But even if the group splits up, and those in back get caught by a red light, never to see the front group again, well, that's just the way it is.
