Nowadays, we can often hear the discussion whether buying cars should be encouraged. Some people suggest that we should buy cars. But others claim that driving cars is not a wise idea. As far as I am concerned, I am in favor of the latter opinion. To begin with, there are few parking lots, so the streets are made narrower by the cars parked along the roads. For example, my father could not find any places to park when we went to the supermarket. Moreover, many drivers do not obey regulations, because people do not pay enough attention to the rule of traffic. For instance, I often see people cross the road when the traffic lights are still red. Last but not least, the growth of new roads’ construction is usually slower than the increasing number of cars. For example, the length of the road has gone up by 20% in 2002. However, the number of cars increased by 50% in the meantime. From what has been discussed above, we could draw a conclusion that encouraging buying cars is not fit for today.
