I haven't read about this being considered a option but I think it might be very smart for TMC to use subscription services for certain features. Such as... Supercharging Speed upgrades Adaptive Cruise Control Autonomous Steering Mapping Cellular connectivity The list goes on.... Of course they could and should be available for outright purchase. But why include the cost of any one of these when they might not be used all of the time just say occasionally like on a long trip. It would lower initial cost without handicapping the car at all. Nothing is for free so why not pay as needed.
