I'm one who use to travel a lot alone by car and I stopped every two hours. It would be a snack stop, meal stop, fuel stop, or restroom stop of all the above. Even with my wife we tend to make many very short stops. There's a reason airplanes have co-pilots. There's a reason in my mind that boats need them. Just to be able to walk around, take a break, look somewhere else, have someone to share the responsibility. From industry experience too, I've seen all the charts and measurements showing drop off of productivity and alertness on a monotonous job after a certain number of hours. Also given reaction and judgement tests and reviewed studies. That mid afternoon drop off, drowsiness, loss of alertness and the middle of the night one are both very real. We once acquired a manufacturing facility that did not give an afternoon break (wasn't technically required in their state). We implemented one. Their production increased rather than dropping and their quality improved. The selection of music playing is also very interesting, finding that which comes between increasing the drowsiness and between taking one's mind totally off the task.
