Back in the 1970s/1980s cyclists had to struggle to carve out their legal place on the roadways. Part of the bargain was that they adopt certain car-like rules of the road, like riding in the same direction as traffic, not weaving in and out, obeying traffic signals, etc. Because of this, cyclists' behavior is more predictable to drivers, thus making the roads safer for cyclists. When I see guys on fixies weaving in and out of traffic and blowing through stop signs I worry that all that progress is going out the window. These cyclists are making the roads more dangerous for themselves.
