imo, vettel has to take majority of the blame
he had pulled along webber and was almost along side when he moved right and tried to push webber further right, off the racing line so he can have the racing line for himself.
while tucking in slipstream and making that overtaking move was all his effort. he was slightly too aggressive/arrogant/hamilton-liked in expecting webber to move aside for him. this is racing, u can't expect anyone to move out of the racing line for u.
it is a fair challenge, but he should have backed off once he realised that he has too much speed to take the corner off the racing line
i have always thought well of vettel but lately i think he has gotten abit impatient. during the post qualifying conference, he was sulking abit like a kid and seem to be complaining a little (although it wasnt totally his fault as he suffered a ARB failure). think he was too eager to prove that he is better than webber, and wanted to break webber's winning streak. not very mature driving. once again, reminded me abit of hamilton
his :screwedu: signal wasnt very impressive too
