I ride my bike like I drive my car. If the situation calls for a rolling stop in the car, the same on the bike. (Many times stop signs are used to slow traffic in sub-divisions, people don't run them at full 25 mph, but slow to 5-10 and only stop if Police or someone else is around.) However, on my bike, if I see anyone else, pedestrians, autos, other bikers, I will take my foot out of the clip so they can see my intention of stopping. My husband rides a Harley and when the group stops at a stop sign, they stop as a group and take off as a group. My bicycle club does the same when there are around 10-20 people in the group. If the group is larger, or the intersection is busy, the cyclists will stop/go in small clumps. This is actually more confusing for the motorists. I think.
