I think the press have been pretty good on this one tbh. no-one has said anything the doctor doesn't say in the video.
the main difference between this and massa is that massa's injuries were a bit less obvious as far as possible outcome.
Sadly in this case it would be a complete miracle if kubica regained full "normal" fuction and feeling which is needed nowadays in F1 with all the switches and buttons they have to deal with in an already difficult enviroment.
I suspect his best case scenario will be enough recovery to maybe carrying on to compete in some other form of racing , ironically , probably rallying.
like i said before , i really do hope i'm wrong and he's back in an f1 car next year.
