The 2014 North American International Auto Show is not the greenest, according to journalist and author Jim Motavallo, who focuses on environmental issues and transportation. He’s a contributor to the New York Times, NPR’s Car Talk, the Mother Nature Network and author of the book "High Voltage: The Fast Track to Plug In the Auto Industry".
Motavallo says at this year's show, only one electric vehicle was unveiled; a version of the Volkswagon Golf.
