> It seems a much simpler and constrained task than driving a car. It's not. Always assume that whatever limit can be exploited to maximize economic return is pursued to the maximum extent by everyone involved at nearly all times. If you do so you will be right more often than you are wrong. An occupation that is conceptually "easy" is made demanding through optimization. Heavy freight trains that navigate hilly or mountainous terrain can rip themselves apart when they are not operated with precision. Passenger train operators can be held to schedules where deviation in either direction is measured in seconds regardless of weather, faults, mistakes, uncooperative passengers, etc. When large amounts of capital are involved always assume that the expectations will be extraordinary and, therefore, difficult to automate.
