Unfortunately, noise pollution is at the very bottom of public agencies' priority list.

Even in Europe, with stricter regulators and less tolerance towards loud and obnoxious behavior, it's way too common to hear tuned motorcycles blasting 110dB engine screeches at 2AM, keeping everyone in the neighborhood awake. In theory it's not allowed, in reality the bikers can do it with impunity any time they please. Drones would at least provide some beneficial service.

It's a lot easier to get a small handful of delivery companies to comply with noise pollution regulations than it is to get a large number of motorcyclists to comply. It's also easier to write very strict noise pollution standards for new technology like drones than it is to write very strict standards for existing popular technology like cars and motorcycles.
