At the moment it certainly seems that way, but it is still early days I suppose. Mercedes are certainly seriously outperforming where I had expected them to be at any rate, whether McLaren can sort their act out remains to be seen.
I'm assuming that he's refering to the pitstop, not the performance. IF you believe Mclaren were better this weekend or not, and if you believe Button would have finished 5th or not, Mclaren's mistake once again cost their driver, it doesn't really matter where Button would have finished, that pitstop cost him points, full stop. It doesn't matter if Mclaren are the fastest car in a particular race, or over a season, that isn't enough to win a either titles. one of the two fastest cars AND a team that doesn't consistently screw up is required to win either title... Hamilton left because, given a great car, the team still couldn't put him in a strong position for the drivers title.
Today once again when Mclaren finally (maybe) showed performance, they still screwed it up. Hamilton made the right choice because if Merc actually get a fast car, they'll probably do something with it. Merc might make consistent screw ups as well, they've called important strategy calls wrong in two races already, but Hamilton has a 3rd and 5th which ain't bad(2 stop instead of 3, and underfuelling him too much). For Hamilton it was an unknown quantity of Merc vs the known(to him) Mclaren, whom he didn't believe in any more, quite rightly.
For it to be unfair one driver would have to have something the other didn't. Both have the same car, for the same team, and the same team orders. Short of having the same driver in both cars its about the fairest fight possible in F1.
The fact Vettel ignored the team orders doesn't make it unfair.
If Webber was faster he would have been able to hold Vettel off.
You're ignoring as per every other post, that Webber SLOWED DOWN< because he was told to, had the team not told him to do this, Vettel wouldn't have caught him as quickly, and there is literally no way at all to know if he could have passed Webber without Webber slowing down. We don't even know if he managed to turn the engine back up, how complicated is that on the car, 3 submenu's deep, or one button. Considering he was defending against Vettel all of a sudden out of nowhere he wouldn't necessarily have had time to focus on and turn the engine back up while he was heavily defending, maybe he did.
They also DIDN'T have the same car, Webbers engine was turned down and Vettel didn't turn his engine down, this meant that Vettel had a significant performance advantage up until at least he tried to overtake Webber.
Throughout the race, when they did have the same car, Vettel couldn't pass Webber, he didn't even get particularly close(in terms of within a second, sure, actually looking like he could get past, not at all). Vettel passed Webber after a couple laps with Webber having turned the engine down, told by his team Vettel is doing the same, and thats it, it categorically was not a fair fight.
