MIT scientists are developing a tiny concept car that'll make it easier to find a parking space in overpopulated urban centers. After you reach your destination, the "City Car," slightly smaller than a smart, uses robot technology to find others like itself and form a chain, parking by folding itself into the rear of another City Car like grocery carts at the cart return. (Nope, you won't able to extract "your" City Car from the chain after they start stacking up; you just swipe your credit card and take the next available). It's not expected to be a big hit with car enthusiasts, but hey, if enough commuters drive these it'll probably be a lot easier for us to find spaces for our normal-sized cars. More at Reuters.
