The way Lewis is backed it shows how great
Rosberg's title was.
Not sure what you're trying to say Dare?
Are you saying Lewis gets preferential treatment over his team mate?
Or..... Car is built around him?
Or..... Team recognise his tremendous natural ability & pace and therefore give him the respect as de facto leader?
I agree that Nico had to exceed his usual work rate, preparation and tactics, plus he had to up the aggression to achieve his WDC.
In that sense his title can be regarded as truly great. However I think Nico realised that bringing that effort and aggression to future seasons still may not be enough to best Lewis again - hence he retired.
Best get out at the top of your game than stay and have your status downgraded to being an also ran in the following years.
At this point I must mention that Lewis has only been beaten twice by a team mate in the points table in his completed 14 seasons in F1, once by Jenson (2011) and then by Nico (2016).
