I think he's getting caught up in his own hype... and unfortunately as soon as he goes on a downward trend the media will undoubtably turn on him... that to me will be his real "arrogance" test. But i think he is a little concieted which is understandable his impact in F1!
But if he ever compares himself blatantly to Senna, for me he will be over the line instantly.
Think about tt... would you get cocky if you were in his shoes?
And for the record, i don't like him (my personal opinion)... i prefer the old school and honesty of Coulthard (yes i'm Scottish too).
