The use of cars is becoming more and more popular in the twentieth century. A large number of the world's population are now able to buy and use cars.
Having a car gives much mobility（活动余地）, enabling the driver to move around freely. The owner of a car is no longer forced to depend on public transport（公共交通）and doesn't, therefore, have to work in a place near his home. Instead, he can choose from a greater variety of jobs and he could change his job frequently.
Travelling to work by car is also more comfortable than having to use public transport; the driver can use the heating in winter and the air conditioning in summer to meet his own need and preference. There is no discomfort caused by waiting for
buses, trains or underground trains etc. With the building of good fast motorways long distances can be covered rapidly and pleasantly. Also, for the first time in the century, many people are able to enjoy their free time to the full by making trips to the countryside or seaside at weekends. This feeling of independence and the freedom to go wherever you please is perhaps the greatest advantage（优势）of the car.
