I ride bikes a lot, including a road bike. That said, most of my riding is not done in groups, though I'd prefer it for safety. Here in CLT there are no shoulders on any of the roads. I stay to the right unless I'm turning or alone. Granted some cyclist are probably idiots, just as some drivers are. Please use care when passing us normal types.
FYI, you don't want to hit a cyclist in a big group, even if they don't get seriously hurt. I'm very even tempered but will go off the handle if I'm threatened on my bike. I wouldn't want to be the guy with a mob after him. Cops will be the least of the worries. Not saying it is right, just saying.
