Piastri stated that the design is legal and has passed all FIA tests, emphasizing it is not the sole reason for the team's competitiveness. He expressed surprise at the wing's behavior, having only learned of it after the race. Max Verstappen has called for the FIA to clarify the regulations regarding flexible wings, while the FIA is currently reviewing the situation. Piastri, now fourth in the drivers' standings, remains focused on supporting teammate Lando Norris in the championship race. The ongoing debate highlights the intense competition and scrutiny within Formula 1 as teams seek every advantage under the rules.
