Trust a group of engineers at MIT to come up with a one-of-a-kind solution to the ubiquitous problem of parking congestion in urban areas – the smart CityCar. No, it's not just another "smart" car - the two-passenger CityCar is foldable, stackable and 360-degrees rotatable! And if that weren’t enough, being an electric car, it's non-polluting as well.

The idea behind the CityCar is to create a network of stackable cars at key points (such as near subway stations and buslines) within a city so that one can just rent out a car from the stacked pool for immediate use. In other words, the cars would be stacked one after the other, much like the shopping carts at a grocery store. All you would have to do is rent out a car (presumably the first one) from the stack, and once you're done with it, stack it again at the nearest available point. Cool, huh?

I think the CityCar would be an ingenious way to encourage people to use public transportation. Not to mention, the extra thrust this will give to the electric vehicle revolution if it ever becomes reality.
