a) Go off grid. Don't use The tech that these cars make.
The problem with this is that it is impractical for people that use see alot of value in using this tech.
b) Pass more regulation.
I am a Hayekian and I believe that regulation will not help with people that know the ins & outs of the regulation, also it's doesn't stop them. It just means corporations are willing to misbehave as long as they can play the legal gymnastics and pay rudimentary fines.
Now, The third option which I see would be the best but isn't talked much about is the promotion, and installation of homomorphic computing or homomorphic encryption.
I am not a cryptographer so I really don't fully understand it's limitations. But adopting this would simply make all these data abuse issues vanish.
Cryptographers, why hasn't homomophic Computing or homomophic encryption been massively adopted?
