Even the manned trucks have their routes all planned by computer. Some algorithm decides the most efficient way to move trucks around. Sometimes a driver will get a seemingly nonsensical instruction to deposit his load in a location other than the one closest to him, but when you query the computer about it, it's got a valid reason why that's a better idea for efficiency and it's always right.
The precision in the GPS trackers in phenomenal. Short range scanners pick up GPS tags on all corners of a bin, a robotic delivery system can place a gigantic item with mere centimetres of accuracy.
The human really is the weakest link in the entire system.
It's unsurprising the military want this. I remember being an outside contractor for PermoDrive in the early 2000s. They were just a small company from a small rural Australian town who developed a system which enabled trucks to store braking energy and later use it as forward momentum, reducing fuel costs by some large amount. Once they had a working prototype, the US military swooped in and bought the company.
