My guess, this is a newer intersection, busily erected in a city/town with most buildings less than a decade old. Youll have these "little" towns out in the country with as many people as cities in other nations. (Im talking little towns, but at the same time, population in the millions). Industrialisation proper has only really touched on them in the last 2 decades as it was mostly coastal cities urbanising like crazy first then push inwards with only a few exceptions. Like Xi'an for instance would be an exception, but most of these places are rural, but people still naturally build hubs which in a short amount of time match the size of many western cities by virtue of population.

In short:

• Shitty planning, this was meant to be a small intersection, no one planned for lights, while Im not saying everyone follows red light = stop to a T and they push the boundaries, people do treat traffic lights more seriously and this is just a massive "give way" shit fest.

• No one gives a fuck - This should be pretty self evident

• Its a 'small' country town/city. People give even less fucks that usual than say if it was in a city where there is a chance there might be more enforcement and more general bureaucracy and order at work.

• It all kind of... works out in the end. I could never drive there, but they get used to it and normalcy is restored and then enforced. This is just how you are meant to drive. If you sat there waiting for people to give way to you, the people behind you think you are in the wrong and the people not giving way to you think you are retarded. Its just how things are now. They would be just as surprised watching a round about elsewhere function where people do give way.
