Okay, so why doesn't it work? You can complain about drivers all you like, but fundamentally car traffic and bike traffic are incompatible. You can't expect a driver traveling at 30 MPH on a 30 MPH road to suddenly and calmly accept that they are now traveling 10 MPH because of the guy in front of them. Swap the biker for a driver going 20 MPH under the speed limit and you're looking at a road rage situation. Sharing the road is a terrible solution. It doesn't work.
