Haha nope. If I buy the car, I own everything that is in it. Installing extra parts or features? Sure, I'll pay for that. Hardware that's already in the car, and disabled just so the manufacturer can try to squeeze more money out of me? Never. I'll either enable it myself, or refuse to support companies that do such a thing if I can't.
Subscription models like this one need to be punished, hard, and/or simply rendered unprofitable. Maybe a few rich chumps are willing to pay, but I think the vast majority of car buyers have no interest in being nickel-and-dimed for the privilege of using hardware they already paid for.
How though? If you buy the car and either don't enable it or bypass it, they still made a sale. Everyone who pays for the feature is pure profit. There's no downside unless potential buyers opt for a Mercedes instead of a BMW. But once they are all doing it, the die is cast.
