It was like that in Lima, Peru. Here in America the contest is "Me First" where everyone tries to cut off anyone. There the contest seemed to be "Let's see how fast we can all go while keeping everything moving." The flow was amazing, and it was more of an ant colony collective than a block and dodge like here. I don't recall seeing a single driver get mad. Two toots on the horn meant "come out, here's a space" not "hey, get the FFFF out of the way!"
