It does make a big difference having a regular occasion to listen to audiobooks.
I listen when going running, hiking, on public transport, and when I can't sleep. It must average about an hour a day.
I don't listen at home during the day, except when I really am excited by a book.
These days just about every trade book is released in audiobook version. Even the back catalog is gradually being added in audio. Occasionally I see academic books released as audiobooks.
