I don't think he's overgeneralizing. I moved to Toronto from Madison a few years ago, and I think the cyclists are a little better behaved in Madison. Most cyclists have lights in Madison, too. As a pedestrian and a driver, I see cyclists misbehave all the time. They go the wrong way down one way streets, they drive without lights or even reflectors at night, they blow through stop lights and stop signs, they pass cars making right turns on the right, they change willy-nilly from the road to the sidewalk or from the road into a crosswalk, and so on. A biker going the wrong way down a one way street had a serious collision with a pedestrian a couple of weeks ago not too far from where I live.
Drivers are worse than they were in Madison, though. Drivers here are very bad about rolling through stop signs or through stop lights to make a right turn on red, or just plain running them. When the light turns green and they're making a right turn, they'll gun it through the inersection even when people are starting to cross. I've nearly been hit twice by idiots making a u-turn while I was on the sidewalk. I live by the police station and I see people texting all the time within sight of it (which is illegal here, I should add). This year has been better, but last year we had a large number of pedestrian fatalities. The police have been talking about cracking down on cyclists, but they need to crack down on drivers as well.
