     In many parts of the world, cars play an important role in daily life and many societies would not exist

and change them as frequently as we change our clothing.

     According to Dr. David Davis, who leads the research team, these predictions are based on the rising

the weather conditions, by projecting an image (影像) of the road ahead on to the car's wind-screen.

5_____ Cars will be connected by an electronic tow bar to the car in front to form" road-trains". "The front

vehicle in such a train burns the normal amount." says Davis. "But all the others in the train would burn about
