The steering wheel is required by law in various places, and is also needed because when Waymo's get stuck they send people out in trucks to 'complete the trip', unstuck the car manually, etc.

There’s also a 100% tax on Chinese cars imported to the US, so hard to say if this demo is a realistic model.

(Detroit is terrified of EVs from China. Detroit went all-in on "more crap per car" and much higher price points. Consumers didn't go for it. Meanwhile, there are good US$25,000 EVs from China from multiple manufacturers. Even Tesla says they want to make one.)
