Petrov still only has 2 more points than Heidfeld, and that's after doing 5 more races. I really think those opening races when Renault had the pace to challenge the podium have scewed these results a bit. Some might say Petrov due to his position in the standings but what about the likes of Sutil and Kobayashi who are less than 10 points behind.
I honestly wish I hadn't voted Di Resta now, while I think he is the most talented he's being outscored by Alguersuari in a Toro Rosso.
If I were to vote again, on the basis of who out of the midfield teams is outperforming their car the most the answer would be Alguersuari.
