To weigh in on the concentrating part I find if I have something to do like when I am setting machines at work which does involve thinking about what I am doing then I actually concentrate well and take in what I am listening to and absorb it. Once I have finished setting the machine and start running it which requires little to not thought (until something goes wrong) that is when I won't be able to concentrate on the book and will usually switch to music as my mind wanders off.

So for things like driving, running, cleaning, cooking etc I will often put a book on and concentrate just fine on what is being said.

With driving and running it does depend on my mood though as both those activities have a certain level of your brain switching off and running on auto pilot which is when I find myself starting to not concentrate.

I'd definitely recommend giving it a try and seeing how you find it as it helps the time fly by if you can get into it :)

I hate them too… to me, they drive like they walk around stores (Especially at Costco!). They’re either very slow and in the way, with no self awareness of that fact, or right on your ass, pressuring you. Almost no inbetween these days.
