Safer Urban Driving Through Confusion?

In an effort to encourage bicycling, improve air quality and slow speeders, San Francisco's Department of Parking and Traffic took out the stop signs in mid-August and installed temporary traffic circles... The result, for many drivers, is confusion. As motorists approach the 15- foot-wide circles -- smack in the middle of the intersections -- they slow, sometimes stop and proceed cautiously. When two or more drivers arrive at the same time, they often stop, look at each other quizzically, wave their arms at each other, then continue... In the end, democracy will decide whether the traffic circles become permanent."
