The futuristic 24/7 operation unfolds across a 13-level garage and employs five car lifts, dozens of lasers and hundreds of bar codes embedded in the floors. Residents who pull into one of the building's five drive-up bays save the precious time of hunting for a spot, instead handing their vehicles off to robo-valets who park the cars for them.
