That either they are completely clueless about what they are supposed to do or the progress of previous years was suddenly wiped out because they can't cheat with the PU anymore. The latter should have a noticeable effect on their customer teams as well. Or you could believe the convoluted BS that Binotto is spewing around. Bring your own Occam's razor.And that's proof of what?
Why do you think Ferrari would have struck any kind of an agreement with FIA if their PU was in fact legal?
