I wouldn't be surprised if right now someone is running an experiment to see how removing features of cars affects the prices; Tesla Inc is dynamically managing the prices and can observe the impact of these features on ultimate sale price. Towards the end of the quarter perhaps they will suddenly add FSD and supercharging for next owner back to these inventory cars.
Hey -- how much should the premium of FSD be? "I'm not sure, let's run a test and see what the premium is on the used cars!"
Also, I suspect the next evolution of the FSD feature set is that some subset of the used fleet will be resold from Tesla to an aggregator / taxi company (uber / lyft / tesloop / arizona taxicorp) to run "limited to particular geo-fenced places under particular weather conditions, potentially with paid operators" FSD pilot where Tesla manages some of the aspects of the autotaxi process and the aggregator manages the rest.
The notion that *I* would send *my* car into a taxi fleet and every once in a while have to deal with the aftermath of someone pooping in my car, bleeding out in my car, eating fish in my car, having a baby in my car, spilling coffee in my car, etc, is just absurd. Nobody (0.1% maybe) who owns a car wants to put up with that nonsense. What isn't absurd is that after FSD- is deployed, some company will offer me more money than the open market offers, to get my car and deploy it to a fleet service where they have a shop that specializes in cleaning the melted chocolate, boogers, spilled warm beer, poop, etc that get left in taxis.
