Orion could work, IF it was programmed not to make left turns over major highways, IF it was programmed to not allow zero radius turns in residential areas, IF it was programmed to do things thy way we were trained.
The only thing is that if they set it up that way, they'd realize most of of time it would follow a similar route to the one we run when we break trace a deliver it our way.
And they could never admit that some stupid truck drivers were doing it right all along.
