About anarchy.

Take away all the rules and let people behave.
"This surprises many people, although mathematically it's not surprising," Hamilton-Baillie says. "The reason for this is that your speed of journey, the ability of traffic to move smoothly through the built environment, depends on performance of your intersections, not on your speed of flow between intersections." And intersections, he says, work much more efficiently at lower speeds. "At 30 miles per hour, you frequently need control systems like traffic signals, which themselves mean that the intersection is not in use for significant periods of time. Whereas at slower speeds vehicles can move much more closely together and drivers can use eye contact to engage and make decisions. So you get much higher capacity."
Well it seems to me that anarchy is nice when few people are present but becomes a headhache when you are among a crowd. If you want to experience what I'am speaking about, no need to refer to mathematics, go to Beijing and drive a car...
