One title to make the grade:
Traffic by Tom Vanderbilt.Read about all six books on Gladwell's list.
One of the heirs to the Freakonomics legacy. A very clever young writer tells us all sorts of things about what driving says about us. I kept waiting for the moment when my interest in congestion and roads would run its course. It never did.
