In a recent NewScientistTech post titled 'Shape-shifting car will brace for impact' a new type of shape-shifting car is discussed:
'A car that can anticipate a side-on impact and subtly alter its body shape to absorb the force of the crash is being developed by researchers in Germany.
The car will use hood-mounted cameras and radar to spot a vehicle on course for a side-on collision. Once it realizes an impact is imminent, it will activate a shape-shifting metal in the door. This reinforces the bond between door and frame, which is normally a weak spot, and distributes the force of the blow more safely...
...The experimental vehicles have radar sensors installed at the front and rear and stereo cameras in the back window. These feed information to an on-board computer that calculates the chances of an impact. "It can recognise if something is going to hit the car, identify where it will hit and its velocity," Tandler says.'
