You notice how it looks chaotic and cohesive at the same time? Its something we in Australia can never manage.Your post reminds me of this. A video I took from my trip to China last year
I think the biggest problem in China is that they don't really understand what cross roads are meant for and where they below. If you put red lights at these intersections because of ped crossing, then it will make it a lot more congested, but for every car to stop for just one or two people along such a wide road is also insane, hence you have this, 'out of my way and I continue' driving attitude.
Yes, another problem is the wide roads that China has as well
