It's not the first time that Hamilton has been heard saying this though- and not just at Mercedes.... It strikes me that he's never happy unless he can go flat out every lap... Which isn't a flaw per se, but it strikes me that it's not playing to the game that's been set!
I was just about to mention that.
Sky kept refering to this as if was one of the biggest stories in F1 since Schumacher returned.
