I've had that thought as well.. basically driver takes a truck/trailer and parks, drones swarm and deliver packages within an N mile radius and come back to the truck... driver moves to next deploy point. Of course the size/weight of some packages delivered via amazon would be an issue in terms of using a drone at all. Not sure about the energy use for flying drones... Land based drones could also work for some deliveries.
