Ahah! Never noticed that! But it would make some sense...
Funniest thing, is to see the whole F1 circus upside down, just because Ross Brawn read this season rules and found a way to go around them, better than anyone else...
I didn´t said he broke the rules, he just knew them so well, that he could go around them, with an air diffusor that isn´t agains the rules, but makes all the difference on the track. It´s been largely discussed on the beginning of the season...
He is, in my opinion, one of the most inteligent and more experient persons on the F1 currently...
