> - Tesla's vision only approach seems a lot more competent than the Lidar suites from smaller Chinese makers. Perhaps I misjudged how necessary Lidar was to achieve safe driving.

Three things can be simultaneously true:

* Tesla's cameras are sufficient for some scenarios.

* Tesla's cameras are insufficient for other scenarios.

* A system with good data and bad algorithmic processing is still going to be bad. The Chinese vehicles almost always fail the tests because they see the obstacle but drive into it anyway.
