I live in a small rural town in Scotland, yet Amazon and others can deliver stuff to my door the next day. In big cities, some companies even offer same-day delivery.
Honestly, I don't need my stuff any quicker than that.
I'm sure there are some genuinely useful niche uses for drones - for example, there was a recent HN post about a company in Africa doing drone delivery of medical supplies to remote and inaccessible locations.
But I don't think it's a good idea to fill our skies with noisy, flying lithium batteries, just so you can get a pizza in 16 minutes instead of 18.
