Keep in mind HW3 and a lot of other hardware components and still made in the US, especially a lot of the hardware that is the brains of the car that other companies will find hard to replicate..
It is also likely that the first thing a new car does when coming on line is, connect to Telsa using a unique Hardware ID and download the latest software... Tesla can probably easily identify cars they haven't made... and stop them driving... they can include security to stop car software being copied...
So the Chinese copier now needs to implement their on OTA updates for find a way to get a version of software running in the cars...
IMO Tesla will keep the latest and most hi-tech components in house and made in the US.....
The Roadster, Model S and Model X will not be made in China,,,, Tesla keeps innovating...
I'm sure the Chinese will steal or acquire some knowledge, designs and ideas, but how far that goes beyond what they could get from a tear down is debatable..
IMO the Chinese government wants Tesla in China for 2 reasons:-
- Help the Chinese reduce/eliminate oil imports...
- Improve Chinese EVs by exposing them to quality competition and new thinking.....
China needs Tesla for at least 10 years, annoy Tesla and they go home.....
How it will play out 20 years down the track is hard to guess, China might even be a very different place in 20 years... it is certainly changing rapidly..
