Which highlights the issue that if there isn't some level of engagement required (or some level of fear/stress that it might be required) your mind/body can reach a restful enough state to fall asleep; in this case of course too, the test driver may not have taken care of themselves properly, had proper sleep, or many other possibilities - which I wonder if we'll get a truthful account of (whether due to Waymo and/or the driver not being straightforward). It's an interesting edge case that you might not think of, or thinking the odds might be "one in a million" and not design for it; I wonder how many driving hours etc have occurred so far (and other statistical analysis to breakdown different contexts) before this "one in a million" event occurred.
