A combination photo shows Armadillo-T, a foldable electric vehicle, folding up its rear at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon, south of Seoul, on September 2. With a click on a smartphone, the experimental "Armadillo-T" electric car will park itself and fold nearly in half, freeing up space in crowded cities. The quirky two-seater, named after the animal whose shell it resembles, is part of a trend of developing environmentally friendly vehicles for urban spaces. Reuters/Kim Hong-Ji
