Though it is a cartoon I notice these is some logic in the way they transform(not the Transformers movie thought that is way to technical and very alien)and it must be quite difficult for the animators to follow draw where an arm is to fold and tuck, how a leg turns into a rocket booster and such

Is it possible for a real world car to transform into a robot and back again?
and can these rules be applied to every day normal vehicles- though they wouldn't be normal anymore
Any mechanical engineers here ever thought about it, it is possible?
closes things I've seen that can change shape slightly are the old Tomcat fighter planes with their scissor wings on aircraft carriers.
I don't even think it's practial really, but very curious in the whole mechanics of it all.
