The only massive advantage the drivers have had this season was Lewis' in KL, he destroyed Nico there and looked like he could have turned it up even more as he did the the end of the race setting the fastest lap by 0.9.
He also destroyed him in Bahrain before the safety car came out and even then managed to hold him off even though Rosberg was on fresh much faster tyres...
He also destroyed him in China where he again wasn't challenged just like he wasn't challenged at Malaysia (other than a minor challenge into turn 1, lap 1)
He hung onto the win at Spain too which is a track he's never been good at.
Then you look at the tracks that Rosberg won / beat Hamilton in, Australia Hamilton won in qualli but car broke before the race had even started, Monaco he sat with Rosberg right on his backside until he got debris in his eye, Canada, Hamilton made a mistake and Rosberg got pole but straight away Hamilton was stuck on the backside of Rosberg up until the breaks gave up, Austria starting from P9 after two questionable mistakes in qualifying either way he made a mistake and had to go from P9 to P4 on the first lap then both him and Rosberg made their ways past the Williams cars and at the end of the race Hamilton was only under 2 seconds behind his teammate (1.1 on the previous lap).
Then at Silverstone Hamilton messed up quallifying with a judgement error, nothing to do with his driving and had to fight his way to the front but regardless of Rosbergs gearbox giving up Hamilton had Silverstone sealed as soon as he switched to the Hard compound tyre but even when they were both on the same compound Hamilton was on average comfortably faster than his teammate
