Is the software upgrade tied to the car, or the individual? I think something like this will require legislation. If I buy a car with a feature, and I am paying extra for that feature, then I expect it to still be part of the car when I sell it, since that was part of the value to begin with. If Tesla wants to argue otherwise, that the software is tied to the individual, then I should be able to either: 1) Sell the software itself to whoever 2) Transfer the software to my next car Both of these should be options, since in the case of #2, the next car may not have the same upgrade.
