Think of this 2008 book as kind of a "Freakonomics of Driving." Vanderbilt asks many questions about life on the road (Is it better to merge early for a lane reduction, or wait until just before your lane disappears? Do traffic signs make roads safer? Do we really drive as well as we think we do? Do trucks cause more accidents? What are the most dangerous vehicles on the road?) and considers them through from scientific, social and psychological aspects. An engaging read, which will have you reflecting on your own habits, as well. Written in 2008, it anticipates, but just misses some of the impact of the most modern technology on driving, such as the latest smart phones (he makes lots of references to Blackberries), but still worth reading today.
