With more and more cars on the road, the traffic _ will happen. How do we see it and how can we solve the problem? We know that the traffic jam happens in many places, especially in big cities. What are reasons for the problem? On one hand, some people think that they should have a car when they have enough money, and then it's easy to go out and they can feel comfortable. On the other hand, a growing number of people hope to use their cars to show off  . What's more, years of research has shown that one of other reasons for the traffic jam is the driving habit. For example, many young people enjoy driving very fast, so they can feel excited. At last, most of them hardly care about the speed rules. Many governments are working at how to make the traffic better. In my opinion, firstly, the governments should educate those people who have cars or plan to buy cars. The governments must make them know that the traffic jam is very serious, and set up a much more perfect traffic system to solve the traffic pressure. Which of the following is NOT true?
The reason for the traffic jam is that people have too much work. The reason for the traffic jam is that more and more people drive cars. The reason for the traffic jam is that some people want to show off. The reason for the traffic jam is that some people don't have good driving habits.
