I did watch the Brazilian grand prix thanks, and after the race Helmit Marko come out and accused webber of holding up Vettel, so that just shows that Vettel is and will always be their number 1 driver. Lets not forget that Webber also eventually let vettel through to gain the place he needed to win title number 3 as well.
I have never seen Webber challenge Vettel since Turkey when they both took each other off. The team may say that they have even rights but clearly Vettel is number 1 in that team. As for Mclaren we will have to wait and see when Perez and Button get a competitive car to see who is the better of the two.
As for Ferrari, they always operate with a number 1 driver and then the team works behind him, since the days when Schumacher first started for them, look at all the drivers who helped him win 7 titles, Irvine, Barrichelo, etc etc.
