FE Hoppy,
That was going to be my point. I grew up in Vancouver and the automatic subway system there was built in 1986. If those freight trains have three people I bet it is part union rules.
I also bet that before I die there will be pilotless planes in commercial operations. Maybe just freight, but they will exist. AND DONT FLAME ME because I do not want a pilotless plane and am not advocating it as I would feel less safe, but there will be a point when I may have no choice.
TME
