My main concern is that you pay a small fortune to buy a car, then get hit with "extras" that require a monthly subscription. Subs that the maker can arbitrarily increase at any time, to any amount. Or turn off completely at their whim. Maybe even download "upgrades" that severely limit the performance or utility of what you have already paid for. Just like with PCs and phones.
This seems to be following the trend of cloud computing for businesses. It sounded like a good idea, but increasingly, the drawbacks and costs mean that it's the wrong decision for many.
