If you've ever seen the movie,The Fast and The Furious: Tokyo Drift,then you've seen this multi-level parking system from Japanese company Sanoyas Hishini Meisho. There are a couple of other companies that produce similar systems, but they all basically stack cars vertically, kind of like a rotisserie but for parking. A conveyor drops the parking spots down whenever you're ready to pick your car up or drop it off.
However, as cool as this thing looks, it might not be heading to the U.S. anytime soon, asThe Japan Timeshas written a couple of pieces questioning the machine's safety.
