I'm not totally clear exactly what Nikki Lauda's role is at Mercedes. While I'm sure he brings a tremendous amount of prestige to the team - its not like they'd be a bunch of nobodies without him. The best I can figure is they need a native German-speaker with the credibility to make Rosberg listen to him. Toto Wolf might be the boss - but Lauda has the F1 championships and the scars to yell at Nico when he's messed up.
As for Hamilton? I really try and like him. But there always seems something just a little bit off about him. When he makes his post-race radio comments, he seems as if he's reading from a cue card. His bopping up and down in the paddock after a win seems a little choreographed, as does his ostentatious kneeling prayer in the drivers' room. Of course, the British press are brutal towards any sports or entertainment figure who they think is getting too full of themselves, so I can't say I blame Lewis for sticking to a script.
I'm looking forward to the rest of the season. Like this race, it promises to be interesting; but not guaranteed to be exciting.
