Why vote him down? Because of his honesty?

I do drive myself. Have for 20+ years. Just drove 1300 miles over the summer vacation, sometimes on long monotonous roads, and I'd be lying if I was paying full attention all the time.

My experience is exactly as he describes. In city traffic, at traffic lights, or just before an exit, my full attention is required and constant (I actually dislike GPS because of this, it distracts, especially if notifications are late, I'm looking at you Google Nav - 'keep left at the fork').

However, after so many years of driving, I have also developed some sort of autopilot/'trance driving' mode. It is typically engaged on long legs, or when extremely tired on a very familiar route (e.g. going home). I betcha if you ask professional drivers like truckers, they'll tell you the same.

Edit: While in this mode, my 'look-ahead' window is maximized. I gaze much further ahead than I do in 'stress' situations. My focus point is definitely way past the windshield, usually several cars ahead of me. I gauge my speed by engine sound, distance to the cars ahead of me, local traffic flow etc etc. As such, I am not convinced that this heads-up display approach is a safety improvement. Sure, your eyes will be on the road, but by requiring a change of focus, you cannot look ahead to anticipate issues/changes/risks.

I have to agree. I do drive like this too over long distances. Anything else would just be too tiring. Maybe we expand the zone of perceived predictability. Fascinating stuff. Good point about having to focus in and out.

This plus Highway Hypnosis [1] show that some of us at least drive without full conscious attention.

Please don't do this.

You're going to get yourself or someone else killed one day. Remember that I can do everything in my power to be a responsible driver I am still subject to the sum total of the risks everybody else takes and driving when you're that tired is an un-acceptable risk.

WTF. People shouldn't drive when they're extremely tired.

Hate to be the type that pulls this one out, but when I became a parent I learned of levels of tiredness I never knew existed, and became aware of a whole segment of society (the parents) who go through most activities in their life at near crippling levels of tiredness. I agree it gets dangerous but it's not feasible to keep them off the road.

That level of tiredness is truly worse than drunk.

And yet, they will.
