Ask HN: As a developer, how can I take advantage of time spent driving to work?

I work as a developer (Java full stack if it makes any difference) and live quite far from my workplace: it usually takes me one hour and a half to and from work by car. Moving closer to my workplace is not an option nor is it using other means to go back and forth (eg train/bus). I feel like my time spent on the road is mostly wasted: I'd like to find something IT-related to do (both listen to and reason about) that can help me learn new stuff. Since I'm passionate about Linux, I usually have a few Linux (or BSD) podcasts to listen to while driving but I found that to be not really instructive, just more enjoyable than listening to the radio or some music playlist. I'm looking for any kind of suggestion from fellow developers who are in the same spot and have found any interesting way or resources to 'spend wisely' their travel time. What resources would you suggest (if any exists) to learn something while driving (much like you would do with a foreign language audio course)? Is it even possible? Has anyone tried or can share an experience of 'audio learning' IT related?
