Oh give it a rest would you? There are mitigating factors and different circumstances applied to any and every given situation, no two instances are the same, which is why it's not so simple as 'someone breaking the rules'. If you want to continue with that though, vettel should have been banned for intentionally ramming Lewis last year, right? but lets ignore that for your sake hey?
Same way Lewis should have been banned for ramming into Raikonnen in the pits during quali right?
