4-year old's take on cab bookings

This was as told by my 4- year old , on how a cab booking is actually processed, right from booking until the cab arrives at the pick up spot.

There is this disappearing (invisible ) drones flying around which goes inside cars and finds out if there are people or not . 

Once we book the cab on our mobile , the invisible drones gets the message. They then tell the driver of the car which has no people in it to go to the location. 

That's exactly how the cab bookings go through and cab come to the pick up point. 

As told by my 4-year old , none added none taken.
