All I can think after reading all this, is large group rides are like lemmings. Technically aren't bikes vehicles and don't we all get mad when our fellow vehicle operators don't adhere to the rules of the road? Mostly in our cases, too close of passes and too high of speed.. but also stop light/sign runners pose a major risk to us as cyclists as a whole. Riding side by side.. fine dandy I agree it shortens passing time and keeps dangerous passes down (sometimes). But blowing a light/sign and expecting traffic to stop for you because your too busy being a lemming... really? How would you feel if 8-10 extra cars blew the light after the red one after another? Must be okay since the guy ahead of him did it right? Your only out 30 seconds to an extra minute right? So must be okay.
