I remember many years ago, I think it was Boeing that showed a mockup of a 737 with the cockpit in the BACK of the plane. Obviously, that didn’t “fly”. Anything that is flying autonomously will be able to be compromised electronically. There’s nothing better than actual eyes when it comes to situational awareness. Not saying humans are perfect, but catching something out of the corner of your eye or other things sensors won’t/can’t pick up. The one comment about the Tesla crashing into the firetruck is very relevant. What happens when an self driving truck has an accident? I drove a rig for several years. Trust me, unless you are running on I-90 across the top of the western US, I doubt it will be feasible. I can see the lawyers lining up already. No thanks to a large or even smaller autonomous aircraft.
