The MIT Media Lab has been working on a folding, stackable electric vehicle for quite a few years now, but it seems those have at least been fairly productive years, as the so-called CityCar has now finally progressed to something resembling a finished prototype. The only problem for those eager to hop into one is that it's a half-sized prototype, which makes accommodating a driver just a tad difficult. It does do a fairly good job of folding itself up though, and MIT expects a full-size version to go into production in 2013. Interestingly, MIT doesn't necessarily see people actually owning the vehicles themselves, but it would like to see them be made available throughout cities -- letting you rent one for a short trip across town, for instance, and not have to worry about returning it.
