Thanks to both RBs at least messing up the start royally.
In a certain way the third place after the start vor Vettel was potentially better than a second place would have been. This enabled RB to put pressure on RG by splitting the strategy.
Feeling a bit sorry for Webber but on the other hand knowing that he isn't nearly as good at tyre saving as Vettel or the Lotus's it looks to have even been also the best strategy from a pure WCC perspective. I'm not sure they would have achieved a 1 - 2 with any other strategy. On identical strategy Grosjean was too fast for this. It was forcing him to pit early which broke Lotus' strategy.
Impressive part on Vettel's side was keeping up with the lap times of Grosjean when he was still on old tyres while Grosjean was on fresh ones.
That was the key to his win today.
