Don't need to buy it, but my personal experience, and latest studies about that "microsleep" confirm that. Similar studies have confirmed the unability for fast reactions to unexpected situations if under dull routine. Considering speed there is, as always, a wide space between two extremes, and as always the optimums is in the middle here too.

Accidents are caused by something unexpected happening.

Well, falling into a second-Lasting sleep causes something unexpected - at least for the driver after he reopens his eyes.

When this happens the guy going the speed limit is much more likely to avoid the incident. that's just simple physics.

That it happens at all is more likely under certain circumstances than under others. Drivers are not roboters, so driving is not physics only.
