It was a great race yesterday, the conditions looked exceptionally tricky at the start but every driver proved their worth by limiting individual mistakes to 1 at the most!
I agreed with the penalty to Hamilton, whether or not he saw Di Resta specifically as he knows where the racing line is and that he is sharing the track with 23 other drivers. Yes his car was on the racing line after the spin and he did well to recover it as quickly as he did, but in doing so the way he did he placed half of his car back on the line.
Strategically his race had been compromised at this point and from such a dominant position. By putting option tyres on his car he was forced to either extend a gap for a pitstop over Button, or make the tyres last twice as long as expected. Being so close to Button following the spin and when the sudden burst of rain came, his only choice was to gamble for new intermediate tyres. Not sure what he would have done otherwise, but I think he was destined for fourth from the spin onwards.
Button was outstanding again, getting into second and maintaining the gap as best he could. When strategy played effect later on he knew exactly what tyres to be on. Called the move to the dry tyres perfectly as well once again. A special occassion to win on his 200th GP weekend!
The second time we have seen the Renault on fire right by the driver, I think it is time for the FIA to step with this one. Next time Nick / Vitaly might not be so lucky, and the marshall getting hit by fragments is a very scary thought too. They have the rearward facing exhausts designed and ready too so only loss will be in marginal performance.
A note about the Ferrari pairing too, impressed with Massa's qualifying performance and then in maintaining it during the race as Alonso made mistakes. Massa's was far more costly, but he coped with the damage well, setting fastest lap of the race. Felipe doesn't deserve to be at Ferrari as Alonso's rear gunner and would be best seeking a drive elsewhere.
Well then things get very complicated - do you hold all the cars in the pitlane till Heidfeld's car is recovered? What if this puts all those cars a lap down or more?
FIA could send a message to all teams "Pitlane will be closed until further notice at 14.20". Allows teams in the pitlane to get cars out or to tell drivers not to pit. Would have been an issue before if people were running out of fuel, but biggest danger would have been in a driver hitting the tyre's cliff.
