Yes, this is normal in managed residential and commercial neighbourhoods. Presumably one would seek out such a controlled environment for testing.

PS. Not sure what city this was filmed in, visible number plates are Shanghai and Yunnan, but he mentions Tsinghua (Beijing).

One thing I noticed in Chinese cities is that they often had a cleaner assigned to each block. They would have a blue jumpsuit, broom, shovel, and wheelie bin.

In the big cities, streets were very clean.
