How have you not understood what I have said more like??? Vettel pushed Button onto the grass at probably over 150mph and if Button didn't back out there would have probably been a serious collision with either driver maybe getting seriously hurt or even killed plus the amount of crowds only metres away could have had debris flying towards them... If that Had been Hamilton he would have been punished for sure!! But thats racing it seems this year.
Yes, completely backed up by the fact that Hamilton was actually involved in an incident that resulted in contact and even damage to a competitors car but the stewards did nothing at all.
Oh wait.
