In China there are actually a lot of regulations, and getting a license is a pretty formal, strict affair. It’s just that no one cares about the regulations; they only care about themselves. “Do I want to turn right from the parking lot onto the main road? Well, I’ll just do it. I don’t care that there’s a car coming at me at 50km/h; he’ll stop, because I’m more important.”
This not caring is compounded by the lack of spacial awareness I mentioned above, and further compounded by lack of enforcement of the existing laws (like not yielding right of way). If it’s not captured on camera, then there’s no enforcement because if you pull a guy over and ticket him, someone is going to lose face. If a machine tickets you and you pay the fine online, no problem.
Thailand seems to be one of the saner places to drive in Asia. I’ll take it over China and India any day! The worst thing about Thailand is everyone invents their own turn lanes. Granted, I’ve only stuck to the toll roads and I’m only considering automobiles.
