Yes, audiobooks/podcasts have been the saving grace of many a road trip for us! I really do enjoy the time machine effect. I also sometimes marvel that the best way to endure the experience (as a body forced to sit still, but taut, for long periods of time) is to escape the body into the mind. Highways are designed to facilitate this trick, but I think also made to curve just often enough to avoid totally mesmerizing every driver into catatonia. It's one of the senses where our desire for pleasure/utility play a game of chicken with our bodily wellness.
