This bubbly concept car protects more than the driver; its next-generation rubber exterior can save pedestrians, too.<br /><br />Traditional metal panels are replaced with soft rubber, which absorbs the impact of a collision. The car is also a shapeshifter, meaning that the rubber panels move and flex, forming a more aerodynamic shape.<br /><br />The futuristic concept was recently showcased at the Tokyo Motor Show, which also featured artificially intelligent cars and electric vehicles. But none as adorable as this rubbery car.
