I listen to audiobooks during my daily commute. That way, I manage to listen to more than four hours of audio content per week. It makes a once boring part of the day absolutely delightful, and I manage to catch up on some great reading. Driving without listening to a book, to me, is wasted time.
If unabridged Trek audiobooks were to be made available, I'd be all over them.
I understand that abridged audios are entirely different animals, and why they exist - but they are no alternative for me. Back in the 90s, I listened to the audio versions of Q-Squared
and Dark Mirror
and found them to be butchered versions of the original. Why would I want this, especially if I have more than enough time to kill when driving?
