The first was a Mercedes A200 that had been imported from the Netherlands to Denmark. It did not have heated seats, something I overlooked when I bought it, supposedly not a deal breaker in NL, but a big issue during cold Danish winters. I would have gladly payed a subscription fee to activate seat heating had it been possible, but the car was originally made for another market, so there was nothing I could do except sell it and buy another one.
The second is my current car, a Volvo, which came with a wifi hotspot. For some reason, the hotspot stopped working after a the car was out of warranty, and I found that I am able to live without it, by using my phone as a hotspot instead. In this case I could have stopped paying for a feature that I no longer need. As cars get more laden with tech, I think it is quite feasible that some initially "fashionable" features will get irrelevant over time, and users might like to have to option to stop paying for features that have lost their relevance. If Volvo would upgrade my current sat-nav to Apple Carplay I would gladly pay for that too.
Having users pay recurring would also incentivize car makers to keep investing in updating their software, and perhaps even install hardware upgrades "free" of charge, in the hope that the user would keep paying a recurring fee to have them.
