Beijing is a government city, so lots of national and provincial officials floating around, their car of choice seems to be a black Audi, but they seem to be branching out into BMWs, Mercedes, and even land rovers. You can tell who they are by how many traffic rules they ignore, but the police typically don't bother enforcing anything on anyone unless they are in special campaign mode.

Shanghai, Shenzhen, Guangzhou are better. Heck, even Kunming and hangzhou are better than Beijing, given there aren't so many officials in these cities.

Diplomatic plates are a similar hazard in NYC or DC.

Literal immunity in most cases, attitude on top of that.

Diplomat black plates are rare though, and they don't seem to drive aggressively, even if they have diplomatic immunity. Saw Hilary's SUV once around the American embassy, weird that they didn't bother blocking traffic or anything.

My families are locals and they know the government plate prefixes and say government member cars are all low key, usually Chinese brands.

That was the plan, but you'll still see a lot of audis in front of the ministries.
