Go stand on a mainline station and count how many driverless trains come in! The technology has come far, hasn't it? Not even any driverless trains on the Channel Tunnel? Maybe a few light ones on single line short tracks. Would you want 400 tons of heavy aeroplane flying low over your abode? Would you conceivably get in one with your family and rely on automatics only? Are pilots such an expensive option compared to all the expense of designing and installing (and proving!) all these automatics. Don't worry about it!
