With the increase in the general standard of living, some ordinary Chinese families begin to afford a car. Yet opinions of the development of a private car vary from person to person. It gives a much greater degree of comfort and mobility. The owner of a car is no longer forced to rely on public transport, and hence no irritation caused by waiting for buses or taxis. However, others strongly object to developing private cars. They maintain that as more and more cars are produced and run in the street, a large volume of poisonous gas will be given off, polluting the atmosphere and causing actual harm to the health of people. Whether private cars should be developed in China is a difficult question to answer, yet the desire for the comfort and independence a private car can bring will not be eliminated.
