UPS uses conveyor belts, bar code scanners, and state-of-the-art automation installed in climate-controlled warehouses to sort packages and get them to your door.

KGH (Korean UPS) pulls a bunch of their trucks into a parking lot (which is also a drive-in theatre) and sorts the packages by hand in the cold.

I’m sure these trucks meet a bunch of mopeds someplace before this stuff actually gets to its destination.
