I feel it would be great if it is implemented. Something like TRANSFORMERS car...:)...Not exactly like car changing to shapes of human ....

It is like a Car that can transform itself from a very compact car to a mid size SUV or a cross over through a touch of a button.

I know there could be lot of safety challenges behind..but nothing is impossible..

The problem I am trying to address is, being a compact car, the traffic jam will reduce , people can drive a compact car easier than a bigger car, accidents reduce, better utility for space as only one driver is mostly in the car...etc.,
