Oak, I wish there was a way to get people in my state to understand what you said about 4 way stop signs. People here have no idea what to do. If one driver is approaching a 4 way stop and gets to the sign before another driver, s/he most often will come to a stop and instead of going on, as the law states, the driver will wait until the other driver has come to a complete stop. Sometimes, there are 4 cars at the intersection, just stopped, with the drivers all staring at each other, waving their hands, saying "you go." They think they are being nice, but it's dangerous. It's bad enough in a car. When you are on a bike, it's harder to tell what the drivers will do.
I live near a very busy 4 way stop sign. It's a pain to have to second guess everyone. This seemed to work automatically in AZ.
