However, Piastri acknowledges that there is still room for improvement, addressing the hurdles presented by recent tracks and the intense competition in the field.
Piastri: I've learned a lot
“In Formula 2 you’re against people who have maybe driven the track once or twice before," he told Auto Motor und Sport.
"Now I’m racing against guys like [Fernando] Alonso who have been to Sao Paulo 20 times in their career."
Another big learning for Paistri has been managing tyre wear over the full race distance, something Norris has been seemingly more effective at achieving.
"I left too much tyre rubber in duels at the beginning of the races," he admitted.
"As a result, they overheated later. Even though the last three races were frustrating, I learned a lot.
"Especially in Brazil, where I was one lap behind from the start because of the accident and drove my own race with a damaged car. The lesson will help me next year."
Despite Piastri being a little hard on himself, McLaren team principal Andrea Stella has been thrilled with Piastri's rookie season.
He asserts that car damage often compromises the aerodynamics of Piastri’s car, which in turn affects tyre performance.
“But the speed is there with Oscar," Stella added. "The consistency is still to come."
