Pensioners near Beijing are pleading for help after residential streets were transformed into a race track by gangs of wealthy young drivers in super-cars.
A spectacular weekend crash involving a Lamborghini and a Ferrari has thrown a spotlight on the boy racers in the heart of China's capital.
But residents of Fenglin Luzhou, a neighbourhood next to the boulevard where the crash took place, say they have been living with nightly races for years.
"I feel angry and helpless. Somebody must do something," said Zhao Lihua, a 64-year-old pensioner whose 11th floor flat gives her a front-row seat to the late-night races involving supercars and super-bikes piloted by super-rich Chinese. "These racers ... are abominable. They cannot be the children of ordinary people."
Mrs Mi, another neighbour who refused to give her first name, said: "I really hate the noise. It makes me want to throw sticks into the road to make the cars flip over."
