@cybrtrkguy It's stays with the vehicle. This is why you can still buy original model s's with supercharging for life and why used Tesla's still have full fsd.
@cybrtrkguy You're missing the unstated next step. Once fsd unsupervised is solved, fsd becomes free included feature on all Tesla's. Then Tesla can transition infrastructure to on boarding fsd for 3rd party manufacturers, at a price.
@WyzeCam I still remember how the cam plus features were supposed to be part of the device purchase. Mostly I still remember how that got back pedaled and the paltry apology of a very limited set of the features that would only ever work on the cameras sold prior to the cut off.
