Having an optional post-purchase power upgrade is one thing, selling it as a subscription is where I personally draw a line and would refuse to consider it.
Even as a one-time fee it’s still wrong, and I’ll tell you why: because if it’s as simple as a software setting and they want to sell it, they’re going to infect the car with DRM to prevent the owner from unlocking it for free, and that by itself is already a violation of the owner’s property rights.
“Post-purchase upgrades” that don’t require installation of new hardware to enable the new functionality are always inherently evil and wrong, because, by definition, you already owned them!
