I don’t rate him particularly highly. He’s not particularly quick, doesn’t have particularly good race-craft and is somewhat prone to crashing. He’s been around long enough now to be doing better than he is at the moment, even at Force India. I don’t think he’ll be here in a few years from now.
So in answer to the question, “What is Sutil’s future”, I’m afraid I don’t think he’s got much of one, not in F1 at least.
Plus, he’s an arrogant so-and-so. I know this doesn’t matter all that much- I mean, Alonso’s doing fine and he’s King T**t :)
