In Chicago I've almost never seen a cyclist stop at a red light or stop sign. Cyclists here feel free to ride on the wrong side of the road, weave in and out of traffic, and cut off drivers. I'm no lawyer, but I fear that if I hit one of these clowns then I'll be completely at-fault. It sucks.
Worst of all, I've never, ever seen a cyclist get pulled over. If cyclists were held to the same responsibilities as drivers, that would be one thing. But they're not, hence the resentment.
