Quote from xtraction :

who is Kubica?

lol he used to be a rally and F1 star (not a F1 champ though)

I always thought Kubica would be world champ one day. He was along with Alonso the most complete driver on the grid in my opinion. Could always get the best out of his car and then some.

Sorry if this has already been mentioned, but Kubica also injured his arm way back before his rally crash in another car accident. He also fell and broke his leg last year.

Unlucky bloke Full of talent.

Well the main problem of his arm is not the movement or speed that much, but well... yes... its about space for movement. I've readed some of his interviews and he sayed the biggest problem for him to drive a F1 car is how small cockpit single seaters have (and also that part of F1 car made for putting a HANS in is very limiting the arm movements). Its diffrent in rally or a DTM car because he have more space to move his whole arm so basically Rallying is for practicing and keeping him still on the pace on the top level, and when he's not rallying he's working on his arm to make it as much working good as possible.

In another interview he sayed he could even make a tests in real F1 car on some kind of tracks and here im gonna quote him: "If i would have to drive F1 car in f.ex. Barcelona race track i can do it even tomorrow but at the current situation Iam not able to drive on tracks like Monaco on the top level, and I need (hopefully) one more year to drive on that track as quick as i can"

Edit: also I've heard some rumours that Mercedes is building a single seater as much close to F1 as possible especially for him to make some more and more testings.
