sorry about the religious war, but crcd made me do it.
"foresaking all bike lane travel" misrepresents the principle and isn't what the Wikipedia page actually says. "ignoring the stripe" just means that you choose the best place to ride based on other factors like speed, visibility, and destination. It sound like maybe you didn't disagree so much as misunderstand. Only the most militant car-hating idealogues would refuse to use a good bit of pavement if it were available. Well, car-haters and people with a dogmatic political agenda of maintaining our access to the roads.
I'm not crazy about bike boxes for a couple of reasons:
1. Cyclists and motorists have to be taught how to use them, and you can't reach everybody.
2. The technique for using a bike box is quite different from the technique for making a left-turn that people learn when they're taught to drive a car.
3. Bike boxes can't be used anywhere that right turns on red may occur, else you'll have cyclists coming up on the right of a right-turning car all the time.
4. Bike boxes should not be used anywhere that right turns on green may occur, or you'll have straight-through cyclists coming up on the right of a right-turning car, anticipating the light being red, but just then the traffic light turns green and presto, right hook.
5. Bike boxes introduce an extra delay for cyclists who arrive during the green, because they then have to wait for the *next* light in order to make their left turn. If they don't wait, but try to shoot a gap in traffic after they're already in the box, they don't really have room or time to negotiate, signal and do it safely.
I understand that some people are intimidated by making the vehicular-style left turn, and feel exposed out there in the middle of the road. In that case, I think they're just as far ahead to use the crosswalk in two stages, like pedestrians, or to push the walk button and cross catty-corner.
