I don&#x27;t know what became of it, but at one point there was a DARPA initiative to do just that for military convoys. The reasoning was that automated trucks would allow soldiers to treat the convoy as a &quot;dumb herd&quot; that would follow and be overseen by a squad of heavily armed and armored &quot;sheepdogs&quot;. This would improve protection for soldiers, while simultaneously improving the efficiency of battlefield logistics.
