A pessimist is a person who always expects bad things to happen. Pessimists think that today's cars are in trouble because they use too much gas. They say the car of the future will be much, much smaller. The car of tomorrow will have no heater and no air conditioning. It'll have no radio and no lights. Tomorrow's car will be an open-air car with no doors and windows. It won't need a pollution control system because it won't use gas. In fact, drivers will push this new car with their feet.

Very few people will be killed in accidents, because the top speed will be five miles per hour. However, pessimists warn us not to ask for pretty colours, because the car will come in grey only.

Optimists are sure that the future will be happy. They think that car companies will soon solve all our problems by producing the Supercar. Tomorrow's car will be bigger, faster, and more comfortable than before. The Supercar will have four rooms, color TV, running water, heat, air conditioning, and a swimming pool. Large families will travel on long trips in complete comfort. If gas is in short supply, the Supercar will run on water. Finally, optimists promise that the car of the future will come in any color, as long as the colour is grey.
