Tesla cars collect lots of data for the company, including the precise trajectory of movement of the car. Henceforth, all the data for Tesla cars in China will be at the tentacletips of the Chinese state.

Tesla will offer the misleading response that it is legally required to store data collected from cars in China in servers in China that the state can easily browse through. That is true, but it evades the issue. The wrong is that the car collects that data in the first place.
