China's auto   production is expected to grow by 20 percent in 2005 to 6 million vehicles  , possibly passing Germany as the world's No. 3 producer. China is the world's-fastest-growing auto market as rising incomes make it possible for millions to buy their cars. Foreign automakers are investing   billions of dollars in expanding production in China. Germany produced 5.5 million vehicles in 2004, the No. 3 producer behind the United States and Japan. London is quickly becoming a major cycling   city after the terrorist ( ) bombings on London's subway and bus system July 7, which killed 52 people. London Mayor Ken Livingstone wants to increase cycling 80% by 2010.  "Cycling is the fastest, cheapest, most healthy and environmentally friendly way to get around London, and more and more people are taking it up," Livingstone said. "The number of cyclists has doubled over the last five years, while those killed or seriously injured has fallen by 40%." Under the London Cycling Action Plan, Livingstone hopes to make London a world-class cycling city to reduce congestion   and pollution. London now has 273 miles of bike roads, half built since 2000. The goal is 560 miles by 2010. How many more miles of bike roads will be built by 2010?
