People seem to think trucks go from one "transfer hub" to another. That hardly ever happens, and when it does, the trucker usually drops off one trailer and picks up a different one.
Most truck routes are actual deliveries or pickups. You go from the distribution center for a supplier and then you do a chain of stops at 4 or 5 stores where parts of the load are taken off the truck and the rest goes to the next stop. Or you pick up an empty and go to 2 or 3 locations to pick up finished product to either be delivered or brought to distribution.
I mean.. there's _thousands_ of hours of truckers on Youtube just doing their job and discussing it. You could watch any of those channels for a few hours and be _lightyears_ ahead of the typical "AV programmers" thinking on the subject.
It's kind of depressing really, how so many silicon valley type people never take the time to learn how the industry works.
