There's a difference between blowing a light or stop sign, versus doing a California stop (roll-through).
When the intersection has good visibility, two-wheeled vehicles are safer rolling through. Why? We are dynamically stable but statically unstable. As soon as we come to a complete stop and put that foot down, our world of options shrinks dramatically. If something's coming toward us, there's nothing we can do but lurch forward, slowly. Not zip out of the way, not swerve to one side or the other. (Not sure whether that's true when doing a track stand... since I have never been able to do one :o )
Cops will ticket us for California stops. Per the letter of the law, in most jurisdictions they're right, and I never argue with a ticket that I deserved (not that I've had any on the velo, touch wood). But I don't hesitate (for example) to exceed the speed limit in my car when *not* speeding puts me at risk of being rear-ended, and the same is true of rolling through stoplights at less than walking speed on my moto or velo. Sometimes I'll drag a toe for the sake of appearances.
When a whole group goes through a light rather than get separated, that's a little tougher. IMO they've got to take their cue from the cross traffic. If the pack is pretty tight, drivers will almost always yield to us and let us take the light. But if not, you're right, once the light's turned red, someone in that pack needs to take the responsibility to stop and split the pack.... and if the only people with maps are in the lead pack, *they* have the responsibility to take it easy until the rest can catch back up.
