I would mostly appreciate suggestions for podcasts to listen to. I've already torn through hardcore history and it was great for learning and putting to use a period of time I would otherwise spend being lambasted by radio commercials and/or getting stressed by traffic. I'm a bit more cautious about listening to an audiobook. I feel like if it's self improvement related I would want to take notes. If it's a novel or some such I'm not sure my attention span would cut it while driving. Thanks.
