Nissan Unveils New Leaf

Available for over a year

Is Nissan's new Leaf the car that will make electric vehicles commonplace? We ask Nikki Gordon-Bloomfield from the YouTube channel Transport Evolved, who attended the launch in Tokyo. Plus, what facial recognition tech can tell about you. And, we chat to neuroscientist Tali Sharot, author of the new book "The Influential Mind", about why she thinks it's futile to try to change people's minds online with facts. Presented by Rory Cellan-Jones, with BBC Online technology correspondent Mark Ward, and special guest Tom Standage, deputy editor of The Economist.
