What is this MotorcycleGP you speak of ? I just tought the Pedro interviews in the movie made him seem more down to earth, less like a circus freak. I never saw any other interviews with him other than the run of the mill podium statements thanking team and sponsors, blablabla.
Crutchlow is the obvious answer...he is "out of this world" when it comes to running his mouth and and not backing it up.
To me, Dani has seemed a lot more relaxed and easy going ever since Puig stopped watching over his shoulder.
