> prohibiting police from using computer vision isn't it either; they'll just buy the data from a private vendor like ring The answer to this would be to legislate what data private vendors like ring can and can't collect. In the end I feel legislation is really the only option; some fancy stuff with crypto like one of the other commenters mentions sounds both complex and error-prone to implement and have it work well, and also risks being cracked either by reverse-engineering or just leaked decryption keys. And if $entity wants to track your car – or anything else – they can probably do so anyway one way or the other. The only real option without having to play whack-a-mole is decent legislation.
