In the past, owning a private car was a luxury thing for most Chinese. Nowadays, private cars can be seen everywhere in China. Cars have become an integral part of people's life: They not only drive to and from work, but also travel around by car. Spikes in car ownership have resulted in more prevalent traffic gridlock and inadequate parking space in some cities, which has prompted local governments to roll out new rules to rein in the number of cars on the road. As air pollution gets more serious, now more and more people choose to buy new energy vehicles. The Chinese government has taken some measures to support the development of new energy vehicles.
