The mercedes is the better car by a hair.
We need to look at where Nico puts the car in qualifying compared to shumacher to understand that Shumacher is the dead weight.
People are grossly underestimating Heidfeld and Petrov. They are doing a hell of a job for 2 guys who have't really settled into F1.
Heidfeld out for a year, petrov just a 2nd year driver, coming off a rookie year where his teammate was of no help to him.
I'd say these 2 are out driving the other 2 guys in the mercedes.
The merc drivers can't hold a good race together. Shumacher was the exception last race.
