I&#x27;m surprised that I never see mention of having one human at the front and a dozen slave trucks driving behind.<p>The trucks behind could be connected wirelessly.  Or they could even use wires. Some sort of machine vision could keep an eye on the truck in front, adjusting distance as necessary.<p>Obviously that takes coordinating trucks going to the same direction but it seems reasonable to have a hub-and-spoke layout where &quot;trains&quot; are broken apart and re-assembled.
