I never quite understood the math behind drone deliveries. In most urban/suburban areas, wouldn't any given amount of battery capacity get you much more operational ability (weight carrying and runtime) for a wheeled ground vehicle, than a drone having to fight gravity? The helicopter drone might be sexy, but I'd expect the right answer looks a lot more like a big Igloo cooler with some casters or treads underneath. The counterargument would be if there's so much overhead in routing that an "as the crow flies" aerial path overwhelmingly beats a more circuitous ground route, or delays waiting to clear traffic. I'd love to see if there's some data making the case either way.
