Lewis Hamilton says the introduction of a new rule clamping down on front wing flexibility at the Spanish Grand Prix was "a waste of money".
Governing body the FIA imposed a stiffer load test on front wings to try to limit the amount teams could exploit their movement on track for aerodynamic advantage.
But Hamilton said: "Just wasted everyone's money. It's literally changed nothing.
"Everyone's wings still bend, it's just half the bending, and everyone's had to make new wings and spend more money to make these. It just doesn't make sense."
The Ferrari driver added that he "wasn't expecting" anything of the change before coming to Spain.
"I drove it on the simulator, and it's pretty much exactly the same," Hamilton said. "A little bit more oversteer in the high speed. Could have given it all to charity, you know?"
A new front wing in F1 costs about £100,000, in addition to research and development resources.
The FIA delayed the introduction of the rule until this race, the ninth of the season, because it expected that the vast majority of teams would be introducing new front wings in Spain anyway as part of their normal development programmes.
A spokesperson for the FIA declined to comment specifically on Hamilton's remarks.
