The video’s chat comments are pretty funny, similar to twitch chat.

He’s explaining the planning, basic physics, and build process. Some of the comments were like: “I took a course on this but still lost”

At 5:00, he’s explaining the AI processing part and made a comment of how this part is “comparatively simple” and the whole chat repeats this (sarcastically). Then most of the people say how they’re lost and how this guy is a boss

Pretty fun video to watch overall.

Thanks!

Everyone else, if you can't read Chinese and want to turn the distracting comments off, it's the switch below the video labelled "弹".

Haha I guess that Twitch style real time response sarcastic chat transcends cultures.

Side question: the road and everything looks super tidy. No trash, all new. Is this normal for China? Or was this filmed in an upscale neighborhood?

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.
