As I said, I rarely saw cyclists stopping at red lights. Today as I rode on the Hudson River Greenway, a short distance before me there were 4-6 cyclists all stopped at a crossroad, I was a little curious how come these cyclists were so law-abiding, as it didn't look like they were riding together. As I approached, AHA, no wonder, there was a policeman controlling the area and had them stop there.

See, there is a reason when more than 1 cyclist stopped at red light
