I lived for a while in one of the most bike-friendly cities and have several occasions burned into my memory where I very nearly killed a cyclist not using courtesy, common sense, or most often following the law. A few examples: riding on the sidewalk crossing the street at high speed having not stopped at all, riding the wrong way down a one way street at night with no lights, passing me on the right when I'm stopped in a right turn lane with my signal on, and many many occasions of running red lights trusting cars with right of way will slow down enough to leave room.

There are lots of bikers who have much to say about traffic laws, but only the ones that empower them while breaking every law that might require more energy or delay. It is frustrating when traffic laws go largely unenforced (and very gratifying when they do).

While it was never a daily-commute I rather liked biking around the city myself, and I get that it's frustrating for both cars and bikes themselves to share the road. But with many on bikes with the attitude of "fuck you I have the legal right to be here AND the rules don't apply to me" acted out, the response isn't really all that unfair (and crazies taking it too far isn't unexpected).

It's hard to find anyone in a public forum focusing on the best way to share the road where sharing doesn't selfishly mean "you sharing with me".
