This is okay too - it's cheaper to put heated seats in all the cars, than to put it in some cars! Enable it via the purchase of an options package. But a recurring cost for the feature? That grinds my gears.

What they could do is allow you to enable that feature later, albeit at higher cost. Imagine what that could do for the used car market? I buy a car where the previous owner hadn't enabled heated seats. I contact the manufacturer and say I'd like to enable the heated seats. Heck, why stop there? The manufacturer may respond asking whether I'd like to purchase an option package instead that included a bunch of other features. This seems reasonable and pro-consumer. Subscribing to a feature does not.
