I agree but it might be worthwhile if it removes loud and annoying delivery vans from cities.
If we ever get to the point where delivery drones might become common place, people are going to lose their freaking minds once they hear the noise. It'll make the normal NIMBYism that pops up every time someone wants to build something in a city to decry the inconvenience of it look positively benign.
