As for Tesla, at least where I am in the EU, there is only one feature offered as a subscription: a mobile network connection for the car. Keeping its SIM card active basically. That one makes sense, I'd say.

Then there are three "features" that you can buy outright after the fact: an "acceleration boost", that one is dodgy, and two levels of their auto-pilot/self-driving. The latter two currently do effectively nothing (especially in Europe that is also true for enhanced autopilot), so they are more or less an option to say "here have some money for future development" if you have too much...

No heating subscription or anything like that. I was going to say that I think the local laws seem to have at least discouraged them a bit, but BMW and VW are trying it too, so I don't know.
