From princesses on shopping sprees to celebrities having sex in the back of the car, the men and women at the wheel have seen it all. And, just occasionally, the secrets spill out …

In the early hours of one morning, nearly a decade ago, chauffeur Jayne Amelia Larson found herself trying to extricate the son of one of the wealthiest men in Los Angeles from the back of her car. The then-chauffeur had been driving the twentysomething party boy up and down Santa Monica Boulevard in her Lincoln Town car as he tried to procure a “transvestite prostitute” for his girlfriend who, he said, “wanted to convert a gay guy”. After several hours, he threw up on the back seat and fell into a drunken slumber, then woke up and tried to urinate in the car.

“He’d been in rehab again and again,” says Larson, recalling the incident that took place just weeks into her new career. “Another driver I later met had been his family’s driver, and said the kid repeatedly did stuff in the car you would not believe, like he went to the bathroom there because he was just so wasted. And I don’t mean in a clean way; I mean in an awful way.”
