Can I nominate Christian Horner for doing his best to cause his team to implode? He's now got the two sides of the garage openly taunting each other. Webber's mechanics were waving a front wing at Vettel's team after the race, apparently. And not in a friendly way.
As far as drivers are concerned, it was a close run thing between Seb and Fernando.
Vettel had easily the best car (aided by his teammate's wing) yet still blew it. He started by making a big mistake in Practice, ruining a set of tyres.
He messed up his start, then blamed it later on the clutch; refused to concede that Webber had won the first corner, thus having to go wide over the rumble strips himself and precipitating his own demise (it's quite possible that this caused the puncture rather than any contact with Hamilton; but even if it was the latter it was self-inflicted, as he was rejoining the track after his excursion and should have made more effort to avoid a collision whilst so doing; then later in the race he drove into Sutil after not being able to get past him fairly for several laps.
As for Alonso, he made if anything a worse start than Vettel (also blaming it later on clutch problems). Then what did he do? He took his teammate out.
Then, after clearly cutting the corner at Vale / Club while passing Kubica, why didn't he just RESPECT THE RULES and give Kubica the place back straight away, like Hamilton would have done? I saw the incident from Stowe corner (aided by the big screen replay) and thought at the time, "He'll have to give that place back". But he didn't, the chump.
As Vettel, he later had difficulty passing a Force India, this time that of Liuzzi, and went off trying, giving himself a puncture and no chance of any points.
So on balance, I voted originally for Sebastien but have just talked myself out of it, since he did at least make a good recovery drive and score some points. So I'm changing my vote to:
Fernando Alonso!
