NBC New York reports that a Manhattan parking garage attendant plunged several floors down an elevator shaft in the Audi he was driving.
The attendant working at the Central Parking Garage fell from the fifth floor and landed between the first and second floor. He was able to climb out of the car before FDNY arrived on scene and was taken to the hospital with non-life threatening injuries.
This sort of personal injury cannot happen with a Robotic Parking System. Electo-mechanical machinery moves the cars into and out of ground floor entry / exit terminals without human intervention. This is an added level of safety for both the public and parking attendants.
