Before the scandal surrounding his private life emerged, Mosley was a high-profile figure at big events, particularly Grands Prix. Since the story broke, he has made one fleeting appearance in the paddock at the Grand Prix in Monaco, where he lives much of the time, but otherwise he has become an F1 recluse.
Sir Stirling Moss today insisted: "He is in a very difficult situation. I can't believe that he's going to be able to handle it that well."
Former F1 team boss Paul Stoddart went further, claiming the FIA would lose all credibility if Mosley remains in office, despite the High Court decision.
He said: "Ask yourself this question, would we be having this discussion now if these allegations had come out against a Tony Blair, a Gordon Brown or another senior political figure?
"We all know the answer - categorically no. The guy would have gone the same day the allegations came out.
"With that damage you cannot hold public office. The head of the FIA is a global public office. If you take the people on a global basis that the FIA represents it is the population of many countries.
"When the Crown Prince of Bahrain says I'd rather you don't come to my country, when the Australian prime minister refuses to have a meeting with you, when the various heads of states of the Grands Prix in particular that Mosley used to attend on a regular basis don't want to be seen with you, most certainly don't want to be photographed with you, you cannot survive a scandal like this.
"There are certain very big public companies that probably won't want to be associated with an institution that Mosley, having been exposed like this, is representing. At the moment I feel the FIA is completely without credibility."
It is understood the Mosley situation will head the agenda of a meeting of F1 teams at Ferrari's headquarters at Maranello in Italy next Tuesday.
