Do you honestly think that they have a limit to what they will sell? I could easily imagine them selling this access to companies that repossess vehicles. An 'ownership dispute' fee that prevents your car from starting and grants additional access to the company. As soon as I typed that I couldn't stop thinking that that has to be a real thing they make real money on already. If it isn't then my guess it is only because they haven't thought about it. Companies will do anything they are explicitly allowed to do or have plausible deniability on to make money.
Yes, I think if they sold that it would have happened by now and you'd have heard about it. Law of big news applies. Also a quick Google would tell you Ford tried to patent this in 2023 and people were outraged over the idea so they dropped it. So I doubt some other car company is doing it and secretly getting away with it.
