This is a very good and not so futuristic concept in the personal transportation. As a part of EV design team , we had tried a similar compact 2 seater EV in our lab and it gave quite interesting results. The fold-able and stack-able concept is something really innovative and makes such vehicle very attractive as Public Transportation in the downtown areas of metropolis. The stack-able concept is mainly useful in vehicles for hire where the car on the top of the stack can be hired. Such technology needs to be commercialized very fast
Yes. As Ryan Chin said, this kind of conceptual small car may be more applicable in Shanghai or Tokyo. It means very less for ordinary house hold use in US.
