Exactly what makes this false claim. Imagine someone gave you a drug and claim that it can cure cancer. It would be a false claim, even though it is possible that in future, it might turn out to be capable of curing cancer, by some specific method of application. The only problem is that that method is unknown today and no indication that such method might actually exist..
So just because in theory, you can strap on two forward facing cameras and call it full "self driving hardware" (because that is what humans have). Would you consider it legit?
