The car is the best invention that makes our lives convenient. If I get on a car, I can go somewhere I want to go easily and quickly. So I can save my time, money, and trouble. If there are no cars, I have to walk for a long time. I don’t want it. And if I have a good fancy car, I can show off my car to other person. It is very important because many people judge a person by a car he have. On the other hand, cars make air pollution. It is very serious these days. Especially in the city, there are so many cars. So air pollution in the city is more serious than the countryside. And if you don’t take care of yourself when you walk on the street or cross the street, you could get a car accident. Especially, in the city there are so many cars. So you have to be careful more.
