I can see drones being used in cities to dump packages into the top of packet vending machines that already exist, that open up with a PIN code. It'd be much easier too because the route can be hardcoded towards the machine.

That's a good idea. Combine it with a DHL Packstation https://en.wikipedia.org/wiki/Packstation in every building, or, in more suburbian areas, every street, and you solved deliveries.

In cities, delivery drivers ship 600 packages/day into packet vending machines, vs only 60 regular delivery, and regular deliveries via usps cost less than $2 for amazon.,

So i don't think a drone , in this high density case could offer much savings.
