That was the plan, however, I as it was announced over the team radio, and Red Bull brought Webber in, I am not sure it would have worked.I seem to remember from comments afterwards that as Button went into the pits he and/or his engineers thought he could get out ahead of Webber. It certainly looked that way to me at the time, watching from Vale.
One thing is for certain, it would not have worked with three wheels on the car. Along with the fuel saving, it is all speculation, all that is certain is that Jenson lost points in the last 2 races, regardless of cause, or how many points we would be talking (my guess would have been a 3rd and a 4th, but at worst 2 5th places)
Taking into account that Seb has had no DNF's yet, and is some way in the distance, and showing no real signs of seriously faltering, I would say that would be enough to assume that neither McLaren driver REALLY has a chance, although they have a chance, and would not be the drivers I believe them to be if they did not still go for it.
As for team orders, not sure that they would help either driver. Lewis is very clear about winning solely on merit, and Jenson has made his position clear, as have McLaren. I have also said before that I would hope that Jenson would do the right thing were he in a position to do so.
Just a little point for the conspiracy theorist, Jenson with the new wing in Silverstone and Germany (which proved to be slower than the old one?) also, Jenson with the new exhaust in Germany (which failed in P2, leaving him less track time) is there already signs of a shift of focus? or should I get my tin foil hat out of the cupboard?
