New technology will have a dramatic impact on cars and highways in the 21st century.
Paras.4-9 Features of future smart cars
With the aid of advanced technology, smart cars will be so designed that they can help eliminate traffic jams.

GPS and "telematics" will make it possible to build smart highways, which will benefit us in more than one way.
Computerized carsÞCars will be bunched into groups of ten to twelve vehicles, only six feet apart, traveling in unison, and controlled by computer.
The application of telematicsÞTelematics could be adopted in thousands of miles of highways in the United State as the price of microchips drops to below a penny a piece.
an environmental boonÞsaving fuel, reducing traffic jams, decreasing air pollution, and serving as an alternative to highway expansion.
