Rossi gets a forth overall in the Gulf race with his buddies,i think it's the second car in the picture. https://www.crash.net/motogp/news/950550/1/rossi-marini-salucci-claim-class-podium-gulf-12-hours
As much as Rossi can do things under the radar, he has been endurance racing and rallying for some time now. He often does the end of season Race of Champions which is a sort of autocross thing. For a while, several years ago, it was thought that is what he would do when he retired from MotoGP but then he didn’t retire.
I'm 100% with you on that front as he should have tried switching sporting disciplines a decade ago when he'd the chance to do so.
I agree, 2010 he could have done it and tbh I think he could have won races in the right car (which he would have had because Ferrari were behind him). He has the detail orientated and data driven skillset for F1 which arguably is probably far more about the car data than even MotoGP. Also he wouldn't have gone to Ducati, and wouldn't have been involved in his best mate being killed which I don't think any human can reasonably expect to not be affected by
