The long haul portion of the journey is much more suited to the AI of today, cars already have enough tech to get this done with pretty good results.
or, as someone with a loading dock, i'd be willing to pay to have someone come out with a bunch of lidar gear and whatever to model up my dock and surrounding area, so i could just provide a big data blob about my dock to the shipping companies, and have their AI trucks pull in correctly every time.
as opposed to worrying about the days when some new guy (with his local knowledge and general intelligence) shows up to deliver and comes in the wrong way and gets stuck for 2 hours.
(there's a new job for you right there, folks, since the model will probably need to be updated every year or two as the shipping companies change their AIs, and changes are made to the surrounding buildings.)
