In the "Gran Turismo" film who is the character of Jack Salter based on?

Unlike Jann Mardenborough, Jack Salter is a fictional character created for the movie, so you won't find anything if you research him. (...) But it's not so clear of an inspiration when it comes to Salter, as he's not based on any particular person. Instead, he's a combination of various people from that time in Mardenborough's life - one of whom might be Gavin Gough, who worked at GT Academy when Mardenborough was there.

Gough is an NLP and Sports Hypnosis Practitioner and he recently reunited in June 2023 with Mardenborough, with the driver sharing a pivotal moment in their relationship on Twitter.

Salter, an ex-racer and former team boss of the cartoonishly evil Capa racing outfit, is not a real person but appears to be an amalgamation of several people. We're not entirely sure who, but it's likely that race engineer Ricardo Divila, sport psychologist Gavin Gough, and team manager Bob Neville (of RJN Motorsport) are among the people bundled into Salter's character.
