While the idea of an Amazon Prime Air drone dropping onto my doorstep and delivering my latest purchase might seem fun and cool, the reality is it simply may not be needed.
The only reason delivery trucks—such as the large brown trucks we see everywhere—only deliver to me around 4 p.m. each day is simply the time taken for one driver to take each parcel to an address. I call this one at a time parcel delivery. It’s the same story for the USPS service. Each day our excellent delivery guy comes to our neighborhood and then spends a long time going door to door.
