So the extras are built into the car and you are invited to pay a lot of money each month to wake them up. I believe Mercedes are also going this way. They will be charging for each wheel soon what happens if you can only afford three? I dread to think what a full steering wheel would cost. The whole scheme sounds like a bit of a nightmare for dealers. Do they turn everything off as soon as they get a trade in or advertise a car with heated seats only to find that once sold the seats have been switched off because nobody has continued the subscription. I wonder if it will work, people buying the base car and adding. I bet the second hand price won't reflect a base car!!

looks like Tesla are already at it . Tesla remotely disables Autopilot on used Model S after it was sold - The Verge
