A "full self driving" car does not exist in this universe, from any company, let alone Tesla, so the fact that they've recognized any revenue against "full self driving" packages does "make the case". If you think the name was meant to mean something lesser, when this $10000 option was added, Elon Musk was publicly saying that there'd be a million Tesla Robotaxis on the road by the end of last year, earning money driving people around while the car owners are at work.
