Of course he is, he knows very well how popular his dead pan answers have become and it's a far cry from how he was at Mclaren or even Ferrari. He's obviously not the only guy with a different public front but he knows excatly what he's doing.
It is Kimi mania, you only had to hear the crowd, everyone I know now loves the guy. Where before he was ultra fast but just a Grey boring Mclaren reboot/replug in of Mika.
He's becoming massively popular.
Haha I went Spa this year and went the pitwalk on Thursday. Kimi appeared and everyone just charged with loads of cries of Kimi! Kimi ! so you might have a point !
Strange how everyone was calm when it was just Grosjean signing autographs at first
