The US has a car culture. In 2010, 95% of American households owned a car and 85% of Americans drove to work each day. This is radically different from the lifestyle most Americans had after World War II, when 40% of Americans did not own cars. China and India are rapidly adopting the US living standard, and cars are flooding the streets. In 2011, China had 100 million cars on its streets, or about 10 percent of the more than 1 billion cars on streets worldwide. On average, 9.51 million automobiles were added each year between 2006 and 2010, exceeding the government’s ability to add roads and prepare for the increasing demand on transport infrastructure. Reacting to this mismatch, cities are establishing car quotas to attempt to slow the growth. This year in Beijing, for example, a car-quota system was put into effect, allowing the registration of no more than 240,000 new cars annually.
