This app has out-of-date information. It is for a utopian world in which every driver follows policy. This would be great if the driver would knock and let you answer the door. They either knock and run with your package in hand giving you less than 1 second to answer your door or they sign your name and leave thousand-dollar equipment requiring a signature on the ground 15 or 20 ft away from your door inviting every hoodlum in the neighborhood to steal your package.
