Robert Penn Warren, in All the King’s Men, wrote that the time one spends in a car, alone, between points A and B, is the one time you get to take a vacation from being you. You aren’t around other people, which define you, so you can really relax.

Warren wrote this in the mid 40s, and the scene was in the early 30s, so if it was true back then, it is even more so now – turn off the cell and cut loose from the world for a bit.
