IMHO, there's too much conjecture as to what a driver's thinking, what a driver can or cannot do, what technique they have and only they have, etc.
All these things are pie in sky, even the title of this thread, Is Hamilton desperate.. is complete and utter conjecture.
Would we use the same in relating a Brawn chassis as being desperate? A desperate design? A new part they added because they got desperate? It's an unreasonable line of thinking to arrive at this conclusion.
Now, an act of driving desperately because of all the contact here and here causing a crash here and here, or a passionate drive to get by so and so, is far from conjecture. OR Brawn desperately got the parts put on in the last second, is technical and logical.
IMHO, is what Ciro means by a sharp pencil... just remember that helmets were invented so you can't hear the driver scream or talk or see their feelings,except maybe the wide eyes of surprise
