An embodiment of this is the Nissan Pivo 2 concept car. It's a whacky bubble-top electric city car concept with a 360 degree rotating cabin and 90 degree turning wheels. It has a much improved motor plus a longer lasting lithium-ion battery pack. And there's more. It also comes with its own small talking cockpit robot, to "advise" you on what’s around, where to park, etc.
Personally, I find 'R2D2' with its rotating head a little creepy. But hey, if I was driving around an unfamiliar city, I might be glad to have the company.
It is hoped that the buzz generated at the show by concepts like the Pivo 2 will get people buying cars again. The Japanese auto market is in dire straits. Vehicle sales have been flat or falling now for 18 months straight.
Many people across Asia, especially young Japanese, have lost interest in cars for a whole variety of reasons. In Japan, an excellent public transportation system has dampened the need for private transport. There are also now an array of many other kinds of consumer goods and services like home computers, cellphones and trips abroad for young people to purchase instead of cars.
