Rosberg goes 0.5 faster in the previous lap, Hamilton ups his pace and stretches the gap out again.
Rosberg really has suffered since the ban on driving technique discussion. He does seem to need to be babied around.
He can't compete with Lewis on even terms and he knows it. His only chance to get past him is using some kind of fuel/tyre/brake saving strategy in the hope he has more of those come the end but, now he can't get all the info on Lewis over the radio, he's totally lost.
