This video has been sped up, if only these systems were this fast. Looking at the space taken up by the shuttles, the only benefit over conventional multi-deck parking is the slightly tighter sideways stacking, and a marginal saving on floor height. Unfortunately car lifts and shuttles are this technology's Achilles heel, they only transport one car at a time. It can take >3 minutes between the time a car leaves the exit enclosure and the next car is brought down: this excludes time taken to enter the correct info on the keypad, store one's shopping, retrieving a rear car from a tandem bay (the car closest to the aisle must first be removed and stored elsewhere), new arrivals correctly positioning their car in the entrance enclosure etc. Clearing a 60-car system can take >3 hours if using one car lift, staff finishing work at 5PM don't want to wait until 8PM before finally driving out. Alternative technology is available, yet solution providers cling to old one-car-at-a-time systems.
