Almost two years ago we profiled the wildly innovative, stackable, electric City Car, designed via the MIT Smart Cities program.

Think of it as a cross between car sharing and bike sharing, where you have the access to a dual-passenger car, but parked in a space not much larger than a bicycle.

It was pretty difficult for people to understand the concept based on images, so the folks at MIT finally produced a video to show how it works.

Considering most people rarely drive with more than two passengers, MIT is looking to introduce a prototype next year. If a pedestrian-only neighborhood is unrealistic, then imagine a City Car-only neighborhood - that’s a whole lot less wasted space for parking that can go toward piazzas and attainably-priced lofts.
