Truck + driver means you have a real person who can kick boxes around and find stuff in the back. Add drones and you have to create an automated drone loading system which works on multiple drones simultaneously. Otherwise you have truck + 2 (3? 4?) drones + person, and the person loads one drone while the other is/others are delivering. That will save some time, but not enough to be a game changer. There will still be kicking of boxes. Meanwhile drones will have to autodock to a charging cradle, land, be loaded, deliver, and then either repeat or autodock again. The system breaks down badly if there's any kind of issue.
