This event has me thinking about job of the behind-the-wheel backup driver. They get an easier job than a real driver, at the cost of potentially taking the fall if an accident occurs. I wonder if the pay is better.
I actually don't think it's really easier. Continuous attention is easier to maintain than hours of boredom only to have to react out of nowhere...maybe.
Train drivers have immense amounts of regulation and systems in place to verify that they are paying attention and actually driving the train:https://en.wikipedia.org/wiki/Sifa
