I personally feel it is NIMBY. They actually provide a useful service. They would like NOT to have clusterfucks because they are dangerous to their operations. The noise level is much improved in this design. I think an honest shot is worth it.
That's not based on actual experience.
And it isn't a useful service, IMO. It's another attempt to sell something that's currently shared (air-space, silence), while not offering benefits in a city. In remote areas, it could offer something, but I'm sure the big bucks are to be found in densely populated areas.
Silence isn't part of the tradeoff, since delivery trucks and vans are much louder. And I prefer giving up airspace to deliveries, since my kids aren't playing in the airspace.
