A composition about cars.

Nowadays, cars often emit black smoke because they use gasoline and diesel as fuel, which is seriously polluted and unsafe. So I want to invent a future car, which is environmentally friendly, energy-saving and safer.

I think the future car should be driven by solar energy, so the body of the future car should be equipped with solar cells. As soon as the sun shines, the car will have energy, not only driving fast, but also not emitting black smoke.

If it rains, you can use the electricity usually stored in high-energy batteries.

Many people can't drive. In the future, cars will drive automatically. Cars can not only identify their own roads, but also automatically avoid various obstacles, automatically identify traffic signals, and automatically stop in case of emergency to ensure the safety of passengers. Each car is equipped with a computer with detailed maps of all parts of the country. Where the owner wants to go, as long as he clicks the place with the mouse, the car will find the best route and arrive in the shortest time.

Nowadays, the quality of cars is not high, there are too many accidents, and cars often break down on the road. In the future, cars can be automatically maintained and repaired. Once a fault occurs, the car will start an emergency plan and automatically search for maintenance points through satellites for maintenance. In this way, passengers are much more relaxed.

This is a dream of mine. I must learn my skills well and realize my dream.
