Emerging from a nightclub near Workers’ Stadium in Beijing at 1:30 a.m. on a Saturday in June, Mikael Hveem ordered an Uber. He selected the cheapest car option and was surprised when the vehicle that rolled up was a dark blue Maserati. The driver, a young, baby-faced Chinese man, introduced himself as Jason. Hveem asked him why he was driving an Uber—he obviously didn’t need the cash. Jason said he did it to meet people, especially girls. Driving around late at night in Beijing’s nightclub district, he figured he’d find the kind of woman who would be charmed by a clean-cut 22-year-old in a sports car.
