content: It's Thailand. And there is no concept of traffic laws. They also have one of the highest road fatalities in the world per capita. To answer your question though, instead of just being smug. My theory is that they have a differnt strategy for traffic. This is because their roads are very, very different. Because Thailand was never colonized by the west, their roads never really adapted to cars well. Cars just sort of happened one day, and were put onto exiting roads. And unlike in America, which had a surge of wealth during its automotive birth, Thailand did not have that kind of funding for its consumer automotive expansion. Also, consider why Bangkok traffic is so bad, to the point of being a mundane cliche. If you just look anywhere on google maps (in Thailand), you'll see roads that make no sense. They just sort of sprawl, wind, and mingle with no concept of throughput. But if you look directly adjacent to their neighbors, countries which are actually very very poor, but were colonized by the french, the roads there are very box/grid like.
