Driving an electric 'bubble' car designed to avoid crashing

General Motors have unveiled a two-seater electric car with a wheel on either side and a communication system that prevents it from crashing.

The futuristic-looking EN-V rises from a crouching position to balance on its two wheels, almost as if they were legs.

It was developed to GM's specifications by the transport technology firm Segway, using gyroscopic and fluid-based levelling sensors to help the vehicle balance whilst on the move.

The BBC's Jorn Madslien went for a test drive.
