Models wave in Nissan Motor's concept car 'Pivo' featuring an egg-shaped cabin atop a wheeled platform that can swivel around 360 degrees, during a press preview for the upcoming Tokyo Motor Show 2005 in Zama, southwest of Tokyo September 28, 2005. Named after the word 'pivot', the revolving feature makes parking in tight spots a cinch, which operates on an experimental drive-by-wire system, which eliminates the mechanical linkages between cabin and chassis to enable steering, braking and shifting through electric signals sent to a central computer.
