I can't understand why they have been so quick to choose "driving miss Daisy" as the reserve driver(still not confirmed ofcourse, but seems most likely). Unless the R31 is as dominant as the BGP001, Nick Heidfeld is not going to fight for the championship(and even not then I'm sure). What about the development? Yes, what about it? Does it not require that the experienced driver has a similiar driving style or else the car will alter to something that might not suit the first driver? Nick Heidfeld obviously has totally different preferences to Robert Kubica(the 2008 season should be proof of that). Anyway, maybe I'm just tired of seeing Nick Heidfeld back, he did'nt impress against Kamui Kobayashi in the five races he contestet last season for BMW-Sauber-F1(after being official test driver for Pirelli). He was outqualified four to one, the one was a lucky one off, since Kamui Kobayashi had car related problems in South Korea.
I would try everything to get Kimi Raikkonen!
(Bruno Senna said that he was not even considering that the will be replacing Robert Kubica, he's just seeing it as a great opportunity to drive the R31.)
