No he is not out of the woods I am sure, but you are right, this article at least gives some hope.
I hope he has all the strength he needs, not only to go through his physical recovery but also to deal with the emotional trauma he will have to deal with.
I cannot imagine how he must feel, knowing he was the direct cause of another drivers death. Of course he was not a fault, but no matter how freakish the accident and no matter how unlikely a chain of events had to take place to produce this outcome, it must be a terrible thing to bear.
I hope he recovers to race again.
