Sorry, not buying it. Quote from your article: "but unless a customer actually orders heated seats in a car, they'll just be sitting around until they're paid for, via a subscription or otherwise."
Sitting around? Where? Oh, in your car, which means they were installed (hardward and elements needed to provide heat, etc..) at the factory and part of the sticker price, which means you already paid for it, but can't actually use it until you pay for a subscription.
Huh? You have to rent something after you bought it? What's next, subscription wheels?
Change my mind.
