Largely depends on the neighborhood and existing infrastructure. My suburb is reasonably compact and Amazon and UPS have large facilities at the edge of town, right off the freeway. FedEx still has to process everything through a facility in the city center. It's a 30 mile RT for them just to begin delivering packages here. I'm sure this will change soon but until it does, there's still a lot of wasted transit time.
