My friendly neighbourhood Amazon driver fills his vehicle with packages, then drives a highly optimised route to deliver those packages to many destinations along the fastest/shortest route. Often when I'm tracking my package, I see that the twenty or thirty deliveries before me are all within a mile or two of my house. At some point soon I expect he'll get an electric van, but other than that, I'm not sure how anyone could get stuff from businesses to people in a more efficient manner.
