Big ego, small...

A small man (physically or mentally) behind the driving wheel of a BIG powerful car provides the self-delusional image of being equally big and powerful. The car has been designed to provide for itself in terms of the required power to operate and function correctly.

An A380 being 'flown' by a man or a supertanker under the control of a few humans. These vehicles too are huge and built to be controlled. The physical size of the 'operator's' brain makes no difference.

That is the preserve of the ego.
