Visit to Tennessee -- a state that brought human evolution to the headlines last century -- to talk about the evolution of the car this century as the LEAF goes electric. John gets a deep dive on the car from Nissan Product Planner Mark Perry while marketing chief Jon Brancheau talks to him how they are rolling it out across the country. In addition, John drives the LEAF all around the city of Nashville and gives you his impressions of this first mass produced all-electric pioneer.
