It's quite an extraordinary season. Rosberg has only beaten Hamilton in 3 races where they both finished and yet leads by 22 points. Of those 3, in one Hamilton had a technical failure in quali, in another Rosberg (deliberately or not) impeded Hamilton's lap in quali and in the third, Hamilton threw away his chances in quali with silly mistakes. Not once has he beaten Hamilton in a clearly fair fight. Leading under those circumstances is bound to make fans unhappy even before the other issues.
One of the biggest surprises for me this season is how little gap is between then in qualifying, forgetting the time hamilton made a mistake aborting a lap Rosberg has been much closer than I ever thought he would. Now people would rightly point to Rosberg making a mistake under pressure in the race, but Hamilton continues to make them in qualifying, which is surprising when he's natural ability especially to be quick on colder tyres is usually so good. Is he feeling the pressure that much to get pole from Rosberg that he's making mistakes?
I don't feel he needs to worry as much about pole, even from 2nd over a race distance he will easily beat Rosberg. Rosberg in contrast should play the percentages, go for 2nd save the car and watch what happens with reliability. That will decide this title now anyway. I think he will over do it tomorrow again and DNF.
