Some questions around changing owner to ensure that the old owner has no access any longer after the car being sold: Is it possible that more than one user can remotely control the car? If so, is it controlled via the same account or has any individual it's own account? Also related to first question what has to be checked or done from new owner to ensure that none of the previous owners or users have access to the car any longer? Especially in case when the used car is handed over from private owner directly and not managed by a dealer or Tesla (who might take care of this already). Where is that managed? Website, App or in-car?
