Looks like some are simply daydreaming while riding. I'm actually surprise that there are not more cyclists being hit. Merits goes to the drivers, not the cyclists IMHO. I see them crossing intersection at low speed without any care for traffic around them. One of the road I take has 3 four ways stops in about 1,000 feet. Granted, the crossing roads are not really busy but many crosses the intersections without even looking or reacting to incoming traffic.
