Did Button say he thought he would have come third?? Lol
Thats what I dislike about Webber, he knows exactly what his position is, he's completely happy to stay and get second, he knows exactly what the score is before he chooses to stay... then he stays because he wants second if he can get it, and the money a title winning team offers a second place driver.
A lot of teams have an 'overtake' button that allows full revs and things on the engine. Maybe RBR have a single button that both over-revs the engine and deploys KERS at the same time, rather than having to press 2 buttons?
I thought it related to a position on the multi function wheel dials, i.e. an engine mode?
