If this were Hamilton, boy oh boy. Suspension of F1 license for mouthing up pirreli.
The thing with Vettel is that redbull know that Mclaren have a tyre wizard in their garage and they don't.
The rb7 is being held back by the conservative pirelli's.
Anyone notice that it was half a second quicker at spa?
The car didn't change much. All that happened is that Mclraren learned about the pirellis in the past 3 races and used that knowledge to gain on redbull.
Having acquired some insight into the pirellis, Redbull are setting back things how the used to be; ie a half second gap.
Now whether they learned what Mclaren has is a mystery. But what seems apparent is that they can't achieve the same result as Mclaren in the same way. Their way of achieving the same tyre result is by cambering up the wheels more than normal.
This is what is annoying redbull. They can't achieve the same exploitation because their car warrants a different process to achieve it.
This could be BS, but i think it's something to this effect.
