I was in Shanghai last month and i must say the drivers there are pretty damn daring and dangerous. They love to zig zag on the highway and on normal roads. Its almost like a norm to them to zig zag without using signal lights and they drive quite fast too. One thing though, they really use their horn at every opportunity and while inside the hotel room, the whole evening is just filled with cars horning each other. But the drivers there don't take horning as a sign of disrespect but here in Malaysia, you horn the person in front, next thing you know he's down with a hockey stick.
