Bernie Ecclestone would have shown Valentino Rossi the black flag for his antics with Marc Marquez during MotoGP's Malaysian grand prix.
Physically kicking out at Marquez as they battle for position at Sepang, Rossi caused the Honda rider to crash out of the race.
The Italian was sent to the back of the grid at the following race, the season finale in Valencia, and handed penalty points.
Ecclestone would have disqualified him.
"Rossi would have been disqualified for sure," the F1 supremo told Gazzetta dello Sport. "Or he would have been shown the black flag.
"What happened is completely wrong."
The F1 chief believes MotoGP's controversial finish to the season, which was won by Rossi's team-mate Jorge Lorenzo as the Italian was unable to recover from his grid penalty, is a "warning to Formula 1."
He added: "I'll give you an example. Let's suppose Ferrari is en route for the title and Mercedes block them with one of their customer teams, what would then happen?"
