When I lived in Chicago there was still a parking garage or two that had a big elevator. They would drive your car on it then raise it up to the level they wanted to park it at, then drive it off and park it. There were no ramps to waste space. Of course, you were obligated to have some greaseball drive and park your car for you. Vertical Vertical Vertical (Three free verticals)
Iv'e seen a similar set up in Japan about 25 years ago. I sat there and watched it like I was a zombie!
I've seen this before. I always wondered about fluid leaking.... I also wondered about a fire, let alone cost effectiveness.... Oh shit I forgot my wallet.... then rotate it back around and down.... LoL
