Well Steph, if for one minute you believe that HAM would not have been penalized in the opposite situation then your fooling yourself. Check Monaco, HAM got two penalties for causing a collision, one of them where Massa purposely turned into him, for being further ahead than KOB were today. (Sidepod, whereas today was front wheel on rear wheel).
Definitely a bias going on with the Stewards can’t be denied anymore.
BTW Rosberg where overtaking of track in the start as well, unpenalized.
