BMW Gina car: a real time shape shifting fabric and wire frame fully drivable concept car

In the video, it can be seen that the front headlights can wink open and closed.
The rear lights can shine through the material. The front body can also be seen to reshape by shifting the wires in the frame. The aerodynamics could be modified in real time as needed.

The advantage of such a car would be far less material used for construction and thus more fuel efficient. It would also have a reduced supply chain.
