It does seem like Ferarri have come up with a wing just to prove how illegal Red bull's cars are, as in "look we can make a wing thats completely ruddy illegal but acts completely different in tests and passes, we could have won a title aswell if we wanted to "
It is completely ridiculous, and I think, lets say, its slightly less refined than Red Bull's system. You would have thought if Red bull's "flexi wing" had been as freaking obvious as Ferarri's despite passing tests they would have been told its illegal.
