No, he was like that before Melbourne. If anything, he's got a little better after Melbourne because we sometimes see a brief moment of emotion before the corporate babble returns. Like earlier in the year when he was asked about his car being terrible and he said something like "yeah the car isn't so good this year, but the team does a good job and the Mercedes engine is great blah blah blah". He's almost saying the opposite in the same sentence, even Coulthard noted this. And the whole Melbourne thing partly happened because he is largely unable to voice his own opinion and allows his team to tell him what to do. Sure drivers should do this to an extent but he is allowed to voice his opinion and it would have saved his skin if he had. This is one of the reasons I don't really like Hamilton as a personality. Great driver to watch and all but he lacks in other areas.
