Thanks, that's helpful. I'm reluctantly considering purchasing a vehicle, possibly even relatively close to new. The ancient beater I drive when the bike won't do the job isn't subject to these issues, and might even be proof against an EMP. Tho' where the hell I'd get petrol in a post apocalyptic landscape is an as yet unanswered question. lol. I like the idea of the 'bells and whistles' of modern conveyances, and do so much in other spheres to limit corporate access that it makes sense to consider how to minimize in the case of a more modern car.
