As I understand it , he was given a penalty for re-entering the track unsafely , but that's not what the stewards seem to be saying .
They seem to be showing him as having regained control , looking in his mirrors , and realizing the Hamilton was coming on his right , steering to the right , to squeeze Ham between the wall and himself .

If this is the justification for the penalty , should it not be a penalty for forcing another driver off track ?

That aside , the penalty seems to me to be as close a call as the wall was when Lewis made the decision to brake .
I'd say the decision would be a cut and dried situation , had the track been one car wider , with Seb gaining control when he did .


One other thought that I had while I watched the podium ceremony was to wonder if Lewis would come under any scrutiny for pulling Seb onto the top step with him , as this was what Michael did with Rubens once , only to receive surprisingly severe sanctioning fines for breach of protocol .
