It&#x27;s something that a lot of professions are specifically trained to avoid.  Awareness is a hierarchy. No one can remain hyper vigilant all the time, but you can be trained to remain in a state of relaxed vigilance. In this state, you can react appropriately to situations and heighten your awareness state as the situation calls for it. If you are in a state of unawareness and are unprepared then your reaction to a situation that suddenly calls for heightened awareness will be very sub-optimal.<p>I think the issue with self driving cars that require a driver to be ready to step in at a moments notice, is that we, as a population are not trained to remain relaxed and aware at all times, nor is it reasonable to really expect most people to be able to do this.
