I've noticed an uptick and
bad cyclist behavior recently here in Philly. I'm one who thinks that it's often okay for cyclists to, say, make a turn on a red light even if it isn't allowed, or go up on the sidewalks at times. But such behavior is only okay if they aren't creating a hazardous situation for cars and pedestrians, respectively. Lately it seems like there are more cyclists cruising fast around corners on sidewalks, going the wrong way down one way streets, shooting through red lights, etc. Annoying.
