Does it have to IT-related? I find audiobooks, both fiction and non-fiction, to be a great way to pass time during commute. The Great Courses offer a bunch of interesting lectures, for instance.
The OP is right to consider professional development during their commute, but it's not the only thing they could do. Instead driving time being professional development time, it could be hobby time. Listening to the news or audio books could free up time spent doing that at home for other things. This assumes, of course, that the OP has hobbies that they pursue at home that could be shifted to car time.
My hobbies are mountain biking and windsurfing but I'm not particularly interested in listening to news or stuff related to those. As for books, I find it far more enjoyable to read from paper rather than to listen to someone reading, although it also depends on who's reading... I really enjoyed a few audio books narrated by Stephen Fry.
