Back in 2009 G.M. and Segway talked about the P.U.M.A.
, or Personal Urban Mobility and Accessibility vehicle. Now it's the EN-V
, which stands for Electric Network Vehicle. G.M. (along with partner Shanghai Automotive Industry Corporation) debuted the thing in Shanghai in 2010, then displayed it at the Las Vegas Consumer Electronics Show in 2011, and now they're showing it off at auto shows, no doubt hoping to get a lot of buzz going for this two-wheeled wonder, which is supposed to be so loaded with navigation and collision avoidance electronics that you can sleep in it on your way to work. (Please wake us up when we get there, okay?)
