> Optimal routing of delivery vehicles for UPS/Fedex etc is also non-compressible to the drivers, so the planners often intentionally generate suboptimal solutions.

Really? That's the first time I've heard that (and I've worked on vehicle routing).

Normally, the driver would get the next address they have to visit and would use satnav to work out how to get there. They don't need to "comprehend" the overall route.

Packages might have delivery time windows attached to them, so the optimal solution calls for multiple visits in the same neighborhood by the same van. This is bs from a driver’s perspective.
