GM and Segway's "P.U.M.A".

You can even drive it with an iPhone!

General Motors may be knock-knock-knocking on heaven's door, but it clearly still has the time and money to fanny about with left-field ideas like Project P.U.M.A. - or the Personal Urban Mobility and Accessibility vehicle.

A tie-up with personal-mobility guru Segway, the Puma is a two-wheel self-balancing 35mph urban runabout with a maximum range of 35 miles on a fully charged set of its lithium-ion batteries. 35mph, in that? Strewth.

Each Puma is apparently driven by two small electric motors – in-wheel motors, if the pictures are anything to go by – and will be linked into to a live digital network giving details of nearby parking spaces, charge points or coffee shops, and allowing for vehicle-to-vehicle communications. Presumably, then a tweaked and enhanced urban-centric version of GM's OnStar system.
