In my final days in Baghdad I came up with a test, one that determines the civility of a country or culture. It's the Four-Way Intersection test. If the country you are driving in can successfully manage a four-way intersection without lights, traffic cops, automatic weapons, or armored vehicles; relying solely on stop signs and the drivers' sense of fair play, than you can rest assured that it is a civilized nation.
Clearly this is a bit tongue and cheek, but I've found that there are very few societies that can do this well. It depends on a certain level of politeness, empathy, sense of fair play, law abidedness; all attributes of "advanced" cultures and societies. Give it a whirl and let me know what you come up with.
