Tesla you can believe whatever they show, more or less, because they're a public company in a developed country, and will be held accountable by their shareholders and, to a lesser extent potentially even by the authorities. Chinese fraudsters embroiled in State propaganda for the communist regime? Not so much.

In any case, smooth movement is helpful, but it doesn't mean at all what the Chinese fraudsters are implying, and people want to believe so badly: autonomous movement. That's not coming yet. Maybe Tesla will manage it eventually. But definitely these CCP-sponsored fraudsters won't.
