I would love to see it actually try to drive in a city like Beijing or Shanghai. I've been to both cities several times for work, and I can say that if it can drive in conditions like that, then it can drive anywhere.
I would not be surprised if China ends up being the first place with self-driving cars at a large scale. Because the road instructure is in general good and new - and with government support (which a company like Baidu has) legislation and infrastructure will be changed to accommodate self-driving vehicles much faster than we would be willing to do it in the west.
"We’ve tested the car at night and day, as well as in medium rain, and – since this is Beijing – in smog of course."

It takes a bit of getting used to as a human driver too but in some ways isn't so bad. The rules work more like walking through a crowd of pedestrians going in random directions than regular driving.
