Of the solutions:

a) Impractical because cars are needed for daily life and there’s no incentive for automakers to not sell your data.. so all cars will unless this becomes a compelling enough product difference to move the needle on profits,

b) Legislation/regulation that creates the right incentives isn’t easy, but certainly doable.

c) Impractical because homomorphic encryption is absurdly computationally expensive, is still not a fully unsolved problem, and.. in what universe do automotive companies implement this far fetched and expensive means of privacy without sone.. err.. regulation?

It doesn’t seem to be superior to option b)
