Just before the end of the Brazil GP race, both Ferrari drivers got involved in a duel that ended with the collision and resignation of both red cars. Charles Leclerc said after the race that he had left enough space for his teammate, while Sebastian Vettel stated the same.
At the end of the race, Leclerc first overtook Vettel, and Ferrari drivers collided before the fourth turn when Vettel wanted to regain his lost position.
Although it was immediately evident that Vettel began squeezing to the left as he overtook his team-mate, we can see in the slow-motion that Leclerc turned the right slightly just before the collision.
Following the end of the race, the FIA called both Vettel and Leclerc to be heard, and stewards said in their reasoning that both racers could avoid a collision and, as a result, neither of them was the sole culprit for the accident.
