Did I purchase the software when I purchased the car? If so, shouldn't I legally be able to transfer FSD from my Model 3 to a new Model Y? I know that Tesla doesn't offer this service, nor anyone else that I know of, but if someone could figure out how, wouldn't it be legal? Or does Tesla retain ownership of the software? When Chevrolet sells a Corvette, the owner can pull the motor out and put it in any car that he can fit it into, and no-one questions his right to do this. Is software intrinsically different?
