Rules of a normally ordered city are put to one side in the twilight world of street racing.
Hong Kong's street racing world – secretly fast and furious
The drivers huddle together to set the route, always at the last possible minute. One of them spots the red and blue glare of police lights and they scramble to their cars, regrouping a few miles away to continue the race.
By day, Eva is a nurse. For one night each week she is also an illegal street racer - one of hundreds in Hong Kong who are bound by their addiction to breakneck speed.
With the engine of her black Mitsubishi Lancer Evolution VII modified to generate maximum power, the 25-year-old is only the second woman to join an illicit club whose members include teachers, businessmen, lawyers and even a Taoist priest.
Most of them wouldn't cross a pedestrian walkway on a red light during the day - jaywalking is an offence in Hong Kong - but the rules of a normally ordered city are put to one side in the twilight world of street racing.
Tearing along public roads at speeds of up to 200kph, Eva is fiercely proud of her secret identity as a street racer - one that she never plans to reveal to her parents.
"They cannot imagine what racing is because I'm a girl - and I'm a little girl in their eyes - so I will not tell my parents. I don't want to bother them," says Eva.
Hong Kong police said there are no figures on injuries caused by illegal racing and there have been no related deaths in recent years, but stress that one fatal case would be one too many.
"Road racing is a highly dangerous and selfish act that puts other members of the public in severe danger," says Inspector Ngai Chun-yip, who heads the illegal road racing unit in the northern territories of Hong Kong.
"What we want to try to do is to make sure that the road is safe,"
Last year there was an 8 per cent rise in the number of illegal racing complaints compared to the year before. Inspector Ngai led 291 anti-racing operations, increasingly using online videos uploaded by racers to help track them down.
Richard, 41, was one of the 1,700 people prosecuted in the crackdown.
Back at the winding road where he was caught speeding, he points at the bushes in which police rigged speed cameras. After 120 hours of community service and losing his driving licence for a year, he says he rarely races any more.
"If I really want to drive fast, maybe I will go to China [and use] the racing track. But not on the roads in Hong Kong."
He says that if he is arrested again he may face jail and would lose his job as an English tutor.
Police describe racing in the city as an ad hoc rather than a large-scale or well-organised activity. The racers paint a different picture.
Morning or midnight races take place every week in several different parts of the territory, while there are also more spontaneous contests when drivers eye a willing competitor on the street or simply take a chance to rip down motorways alone.
Beneath the racing community's camaraderie lurks an undeniable sense of the status that cars and racing bring.
"There are too many rich people in Hong Kong. All my friends race, all own sports cars. Most of it is to show off," says Nick, who owns a Porsche and a Ford Focus rs500.
With the cost of cars and modifications, faster wheels and engines or louder exhausts, running into hundreds of thousands of dollars, it's an expensive, as well as a risky, way to make a mark.
Amateur racers have long been lobbying for an official racetrack in Hong Kong, which they claim will stop people racing illegally on the streets.
Some already cross the border into mainland China to use a circuit where two races over a weekend can cost as much as Dh36,700.
Others admit a track will never replace the thrill of racing on public roads.
"You cannot match the excitement," says Nick. "Some people will always race on the streets."
