Cars or not

Since the economy and the level of people’s lives grow day by day, most of the people prefer owning high-tech and advanced cars. Also, many people love those kinds of cars such as jeeps and cross-country cars which have bigger exhausts and expend more gasoline for traveling at the weekends and vacations. However, there is a point of view illustrates that high-tech cars mean high-priced repairs. Besides, due to the booming market in the developing countries, the oil the cars need is getting more and more and the price of gasoline is increasing. In some big cities in the United States, many traffic problems like traffic jams appear there. Cars are unefficient there instead of increasing traffic speed. The expense of parking is increasing, especially in New York. Using cars is also one of the most important reasons for pollution in some developing countries.
Considering all of the reasons, whatever in economy or environment, do cars still bring more advantages to people or we should try to abandon them?
