I do wonder if drone delivery will take off (heh). A lot has been said about the disadvantages, but one also has to also wonder about the advantages. There's a point at which things are "good enough", and small improvements aren't really worth the costs. How much time would using drones for the last couple kilometers save? A few hours? Local delivery trucks tend to make rounds every day, so it really does seem like the maximum amount of time drone delivery could save is one day. Will the cost of operating this (not only monetary, but also organizational, and in terms of noise pollution, drone repair, the occasional package/drone lost, etc) be worth the whole one day faster delivery to customers? This, especially considering drones can't deliver everything, so trucks would have to keep operating. Truck's are large— economically what makes sense is to have them full of packages and with a whole-day schedule. Would drone usage offset enough deliveries to cut a few truck routes? Would they be enough to make it all worth? A lot of questions in the air (heh).
