While the McLaren wing passed the FIA's standard static flexibility checks, Marko pointed out that the regulations also prohibit significant bending during actual racing conditions. "That wing bends in the race," he claimed, "and it gives them an advantage."

The FIA intervenes following intense scrutiny of McLaren's controversial rear wing design, which rival teams claim breaches aerodynamic regulations.

F1’s regulations limit the amount of flexibility permitted, but teams try to find ways to maximize this to improve performance.
