I think everyone has the right to enjoy a better life. The private car gives us a much greater degree of comfort and mobility in our life. With a car of our own, we can avoid going to work by crowded buses or subways. Moreover, having a car also means that we can enjoy the weekends and holidays better. With a car we can go wherever we like, even to places where the regular buses and trains do not reach. Therefore, owning a private car should be encouraged by our society.
