It definitely is from the perspective of energy, but I think these mobile surveillance devices are their own national security threat. Admittedly, this applies to all modern cars, but EVs probably get away with more -sneaky- smart features that have unverifiable data handling.
There’d need to be some very hard core vetting and attestation to be even remotely trustable.as an individual i have zero issues with Chinese cars spying on me. I have an issue with my ISP, Google etal all spying on me and reporting back to the Aus Government. The Aus government is the one who wants to do me harm.
I do agree that at government and defence forces levels it might be an issue.
Perhaps you believe that the Australian government is trying to harm you because foreign companies have led you to that belief with their personalised algorithms.
In any case, the stronger privacy laws would help against both those types of problem.
