Audio books have been discussed a bit before, but I never saw a list of recommendations. What books are good in an audio format (especially ones that can be listened to while driving)? I commute 45 minutes a day and would like to put that time to good use.
ETA: I'm mostly interested in non-fiction (goal here is to learn useful stuff, as opposed to entertainment).
If you are going the Audible route (it was well worth it for me) you can pretty much start with "what book would I like to hear". My hit rate has been very high for certain categories, e.g. popular non-fiction, investing books, much sci-fi.
On the other hand, some audio books are only available through services like the NLS or Learning Ally that you need proof of disability to use. Occasionally people share them online, but there are several LW-relevant ones I've never been able to find.
