Absolutely essential reading. In Malcolm Gladwell's 'Blink!', he exposes how we think about thinking. In 'Traffic: Why we drive the way we do (and what it says about us)" Tom Vanderbilt exposes how and why we do things on the road and in our cars. Interesting concepts from 'why more dangerous roads our safer', to explaining why the 'other lane always seems to move faster', Traffic, is a must read. For anyone that wants to grasp the complex idea of the human element on the road - I suggest 'Traffic' is the book for you.
