Would the Cars 2 WGP work irl??

While watching Cars 2 years ago as a kid I noticed these cars are not all the same and as a racing fan I found this very unrealistic because in the movie they tried to make the race fair with straightaways for the F1 car, technical turns for the GTSS cars, and a dirt section for the Rally car. But in the end I feel Francesco should’ve just taken the W and moved on because he’s faster than all these cars and I’m not even gonna mention the fact lightning BEAT him in Porto Corsa because he’s a S T O C K car in which would get absolutely smoked by F1 cars. And in the Tokyo race there’s DIRT and something I know about F1 cars is the have flat tires and can not go on dirt at all so what would happen if Francesco crashed or something from spinning out?? It’s completely unfair to him because all these other racers were capable of driving on dirt (I think) and uhhh yeah. I’m just asking a question here
