Some experts feel that the automobile is to “die”. They see a day in the not­too­distant future when all autos will be abandoned and allowed to become rotten iron and steel rubbish. __小题1:__ They think that the car will remain a leading means of urban travel in the near future.

_小题2:_ It should become smaller, safer, and more money­saving, and should not be powered by the petrol engine. The car of the future should be far more pollution­free than present types.

Regardless of its power source, the auto in the future will still be the main problem in urban traffic jam. _小题3:_

The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the freeway. _小题5:_ It is guessed that an automated freeway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present­day freeway.
