I think all of this 'saving fuel' rubbish is a load of crap.
They're supposed to be fuelled to the end?! no?
Understandibly they want the cars to be as light as possible. But surely if you put a little bit more fuel in, then you can run the whole race with the engine turned up! Thus, being able to race flat out for the whole race!...and not have to slow down at a time when others could make a pass at the end of the race.
The FIA should make them run with the tanks 'over-full' so as to stop any 'hidden' team orders like 'Fuel critical', which we all know meant 'slow down and stop fighting'.
Basically they will never stop team orders as it will all be done in the board room before the race.
Sure I heard Horner mention a little 'agreement' they have at Red Bull about who ever leads after the pitstops, the order stays the same to the end. Did anyone else hear that a couple of races ago?
