I'm of the variety where I consciously listen to every word, thinking it wouldn't be in the book if it was irrelevant. That may seem extreme, but the difference between missing a word and missing entire sentences is tiny when it comes to audiobooks and podcasts. There's a lot of rewinding.
So when do I listen to them? When driving, when eating, when exercising, when doing chores that don't require much thought (laundry, folding, dishes, cleaning, ...), brushing teeth, walking to somewhere... there's a lot of time to listen to books and podcasts, even though it becomes pretty much infeasible the moment something requires actual thought, and even though I don't commute anymore.
