The linked article I'm afraid doesn't come close to telling the half of it.
Hunt always flew British Airways and always stayed in the same hotel where the BA air crews (to include the "stewardesses") overnighted. Which made the hotel's lounge his private meat market. Over his seven year F1 career, he averaged more than one conquest a day, often two at a time.
Hunt frequently staggered into the paddock on race day obviously having come straight there from another tryst, Babe Ruth-like, reeking of sex and cigarettes. If it affected his driving, no one ever noticed.
According to Gordon Murray, Hunt was late for the driver introductions at Fuji in '76, where he clinched the WDC after Lauda retired due to the downpour, because he was in the gent's room being serviced by a Japanese flag girl.
At the '77 Canadian GP, Hunt shunted (see what I did there?) then punched the corner worker who was trying to get him off the circuit and headed in the direction of the pits (video here). The FIA fined Hunt $2000 (+$750 for walking unsafely back to the pits) and the corner worker sued and won in court.
He had a German Shepherd he frequently took to posh west end London restaurants with him for dinner. He'd even managed to get the dog an associate membership at his golf club so "Oscar" could "take the air" with him as he played his round.
When Hunt was racing for Baron Hesketh, whose chief occupation was burning through his inheritance, His Lordship created a hospitality division for the F1 team that made sure alcohol and loose women were never far away or in short supply. And if you needed to get somewhere, there was a fleet of Rolls Royces, a helicopter, a business jet, and a yacht, yours for the asking. Add to that the ass-kissing that comes standard with being an F1 driver and you can see how easy it would be to let the celebrity go to your head.
It shouldn't surprise you that Kimi Raikkonen sometimes races snowmobiles under the nom de guerre "James Hunt."
Sorry, I meant Murray Walker.
