Very necessary. Britain doesn't know that America has no cars, just as America has no legs. Instead of learning to drive because there are many things to do here (besides, it is not easy to find someone to teach you. First of all, you have to buy a car, and others have to take you to see it yourself, otherwise few people are willing to borrow it from you. It is better to learn well in China, where it is easier to get a driver's license. Besides, driving training in China is much better than that in the United States.
