I wonder how this compares in total efficiency to traditional truck-based delivery. I could see it going either way -- trucks can presumably move more goods further per unit energy, but you can't take full advantage of that unless your destinations are fairly close together. Otherwise hauling everything with you for the whole trip becomes rather more of a liability.
Drone delivery can be done entirely autonomously, with drones receiving packages from an automated feeder and landing on charge pods between delivery rounds. The drones themselves are quite cheap and the only wear item is the battery.
