Let's say there is an airport somewhere flat and with no trees, so let's assume LOS (Line of Sight) conditions. We want to provide a courtesy bus system, 24 hours a day, to drive around at speeds no more than 10mph. Shuffle people around terminals, to rental car lots, to designated ridesharing collection areas, etc. Couldn't the buses be piloted remotely?
