Actually, I would suggest not focusing your attention on evolutionary anthropology while you're supposed to be piloting a multi-ton vehicle at high speeds.
When you're driving a daily commute your mind is going to wander unless you have extraordinary focus control / mindfulness training. It's not obvious to me that it's more dangerous to have it directed to evolutionary anthropology than to what you're going to do when you get home (or wherever else it wandered).
There's a difference between accidental mental wanderings and deliberately focusing on a sped-up textbook.
If you're listening to a sped-up textbook without focusing on it, I'd say you won't get much out of the experience.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
