I have a noob question to ask! In the Transformers movies, how do they get the vehicles to drive around but without appearing to have drivers inside them? I know this must be like a really old special effect cos it's been done so many times before on film and TV (e.g. K.I.T.T. from Knight Rider etc.) but I've always wanted to know _how_ they do that?

Are the vehicles remote controlled or are there stunt drivers in them who are hidden from the camera or somehow optically (nowadays digitally) removed? When I was a little kid I assumed that KITT was radio controlled, but now that I think about it, I don't think I ever had any evidence or reason to assume this. And now when I think about it, it wouldn't it probably be stunt drivers? I can't imagine someone driving a Concept Camaro on two wheels via radio control.
