I actually agree that Lewis did something wrong and that he gained advantage even if he did give the place back but the penalty is absolutely undeserved. Lewis gave the place back but jumped straight into Kimi's slipstream thereby giving him an advantage compared to where he was before he went off. In my opinion if you go off and gain a position you should give it back and not in such a way that just sets you up for a pass straight after. I will say again I don't agree with the win being taken away from him though....
