My first thought was that the other companies don’t use two drivers for an extra set of eyes on the road but to have an extra set of eyes on the driver.
Human brains were not designed for this kind of task. Everything about the task prompts a resting mindset but the task requires 100% full concentration for hours.
Regardless my point was more related to the fact that an additional driver likely would have prevented the primary driver from watching a movie on there phone as opposed to watching the road.
Whatever they’re supposed to do in this instance the driver wasn’t doing it.
Re: second driver, I agree, but that costs twice as much.
Seems pretty obvious who to blame to me.
