Pretty harsh , weighing Vettel just as conditions are changing , but not good to not follow instructions from the FIA employees , so a penalty will be applied .

Hamilton is out chastising Sirotkin for attempting a pass into the final corner with them both on out laps .
I was in the Lewis corner on this one , thinking he had only realized Sirotkin was coming fast at the last moment , and had tried to dive inside to get out of his way .

But , rather than an act of respect , it was the ultimate act of disrespect , where he is essentially say to Sergey that he should stay in line and not get in the way of the big boys .
He dove inside to balk the Williams driver deliberately .
He has admitted as much , so a penalty should be applied .
