I’m not sure its fair to criticise another member for posting the question. This is after all an F1 forum and we are all fans here – its implied that we wish Kubica a speedy recovery and hope that he gets better. There is however, nothing that we can do about it.
Personally, I don’t think this is the end of Kubica’s career. He’s a great racer and he’ll be back, injurys permitting. By the sounds of it he’ll be out until the European season – so i’d guess that Senna will be in the car as he has the most recent experience. Then again, i’d also say that Grosjean is a faster driver. Perhaps Renault will have a shootout between the two to find out.
The other option would be to have a new driver come in, but to do that would be to defy the point of a reserve driver in my opinion. As much as i’d like to see someone like Heidfeld have a go, Senna and Grosjean are contracted to and therefore should rightfully have the seat.
