I'm not sure if these truck will ever be ready for Prime Time. Automated Driving faces a huge learning curve for the machine, and it never really stops. That is one part that gets overlooked. You will never be able to point to the finished AI vehicle and say, "Now it's done. It has learned all it needs to know". There is just too much for it to know. I think we will see AI Trucks/Cars, used in certain specific places, in certain very specific ways, but I don't think they'll ever "Take Over" Like Electric Cars, they are narrowly defined 'niche' vehicles. Inside their Niche they may be superior, but stray out side that narrow corridor, and they will fail.
