You’ve just caught the “red-eye” flight home. The baby in the next row screamed all of the way, your in-flight meal was awful, and you’re beyond tired. You drag yourself off the plane and schlep your heavy baggage over to the car park only to realize that you’ve forgotten where you parked your car. At times like this, wouldn’t it be nice if you could just have your vehicle magically appear? Well, if you’re at Düsseldorf Airport in Germany you can. That’s because “Ray” the parking robot concierge installed there knows when your flight arrives, picks up your car in its mechanical arms and delivers it right to you.
