On the front I think there was nothing unusual, just RBR and McLaren switched roles. In the first few laps after the start (and the restart), McLarens (RBR-s) were much faster, then on the long run RBR (McLaren) closed the gap. Vettel I don't think was a single bit luckier with the safety car than Button and Hamilton. They were all lucky as they could just do their pitstops before the field got tighter. BTW I think this race showed how wrong the Vettel haters are. He did an excellent job coming up from 6th to 2nd. And Hamilton couldn't win from pole btw
Clearly it's not about that, drivers have to be 100% all the time to win. Button did it. On one lap he was 1 tenth slower than Hamilton, but in the race he gave him no chance at all. Good job!
What I was unhappy about: Grosjean's early retirement, but I can't blame Maldonado for it, if he had the inside line there, Grosjean should have let him pass. But it'll be interesting to see what this guy will be able to do in the Lotus. Raikkönen's pace, well, wasn't bad, but wasn't as great either. He was somewhere around the Saubers' pace. (which was quite impressive for the Saubers)
I was happy to see Williams having a car that is good in the race as well, we've seen Maldonado and Barrichello a few times in Q3 last year too, but this time they could stay there. Too bad for the last lap accident, he did want that P5 very much, and I hoped to see him getting it. Again we can't blame Maldonado for not sitting there and accepting 6th. He clearly had the speed over Alonso and since this is racing, he tried everything.
Mercedes was quite disappointing imo, it seems their car isn't working as well with heavy fuel load. They were slow from the start, even if Schumi could keep P3 until his gearbox problem kicked in.
Not a bad race all in all, I hope that the season won't go on like 2009/2011 though. Though I like Button, I would like to see Vettel, Hamilton, Webber taking their place in the fight. And hopefully some others too. (at least for some race wins)
