In the near future, the nation's traffic scene may be characterized by the widespread use of ultracompact cars.
According to the government and automakers, this will mean lower carbon dioxide emissions, less congestion in the cities, greater mobility for the elderly and a renewed enthusiasm for cars among young people.
The tiny transports will come in either four- or three-wheel versions that can carry two adults. They will be smaller than the "kei" generation of minicars, which are limited to engine displacements of 660cc or less.
