What to hear on the interstate?

Road trip! Next week I will be taking the '97 Land Cruiser and will add a few thousand miles to its current log of 126,000, while heading from New York to Salt Lake City. Ninja will be riding limo-style in the back seat in his Ruff Rider doggie seat belt, likely with his paw resting on the window sill most of the way.
This will be my longest drive yet. I have done NYC to Atlanta but with a number of vacation-y stops along the way. This time we are purely driving to move from one place to another.
I have been building up my library of audio books to keep me entertained during the drive. Here's my current list, in no particular order:
The Greatest Show on Earth (Dawkins)
Proust Was a Neuroscientist (Lehrer)
Brave New World (Huxley)
Hitchiker's Guide (Adams)
The Copper Bracelet (Multiple authors)
The Age of Empathy (de Waal)
SuperFreakonomics (Levitt & Dubner)
What the Dog Saw (Gladwell)
The Lakota Way (Marshall)
Ultramarathon Man (Karanzes)
The Anatomy of Peace (Arbinger Institute)
iWoz (Wozniak and Smith)
The Art of Mindful Living (Thich Nhat Hahn)
These are all unabridged so we have 100+ hours of listening, and I like having a buffer well beyond the travel time (knock on wood) just in case I'm not in the mood for something or just don't like a particular book. I have linked to the Amazon pages above, but the Audiobooks are all from Audible.com (I believe now owned by Amazon, anyway), and you can get to the Audible downloads through the Amazon pages.
Any suggestions regarding where to start? I have just listened to a bit of iWoz and so far it's light, breezy and cheerful, and a bit of Writing Down the Bones, listening to which makes me feel like I'm having office hours with a wise college professor in a well-worn coffee shop.
Alright, more from the road! (Or perhaps sooner)
EDIT:
P.S. On the subject of Audiobooks, if you want a real treat, listen to John Hodgman's The Areas of My Expertise in audiobook format. Hodgman and Jonathan Coulton do a performance that is more performance-art than book-reading. It's not 100% hilarious the whole way through, but it's quite an experience and an exhibition of the limitless nature of the audiobook format. In finding the preceding link, I noticed that they finally released the sequel, More Information Than You Require in audiobook format, and I will be downloading that now and adding it to my list.
