I would be more than great to see MS race again, but I don't think this can happen, except if it came to something unpredictable and there was no other possible solution. I do think the second option in the form of giving advice and stuff is far more possible. I think he is already searching for the new f1 talents...
No matter if he ever races again or not, he will never completely dissapear out of this sport, he loves it too much
