I know that i'm not going to be popular with this but i think Hamilton was at fault (yes im a Ferrari fan at least with these pilots, the Alonso-Massa team was a joke). Let me explain, Ham was outside so he could take a longer line and arrive at a higher speed, what's more, he could also maintain a higher speed in the corner, on the other hand Vettel chose the inside (which was probably the cause for the situation in the first place) behind very close to Raikkonen, Rai wasn't on the ideal racing line either so he was also slower mid corner than Ham, therefore Vettel was the slowest of them at that point. As they arrived at the chicane Ham was alongside Vet but wasn't in front, at this time both of them looked to the apex of the left turn (at least thats what they usually do) so Ham saw Vet but not the other way around because Vet looked to the left. Now they are both at the apex, Ham is still slowing down, but Vet was ready to step on the gas ( i think) but suddenly Ham was a bit ahead and made Vet to take a tighter line but he couldn't. In my opinion Ham shouldn't have been so close to Vet, if he stuck to the outside a bit more and then try to overtake Vet on the inside, he would have probably succeded anyway. I wouldnt have given them a penalty either. This situation wasn't worth any penalty because it wasn't illegal in any way, but still it was more of a fault of Ham than Vet, he should have given more space to turn, F1 cars or not they have limits too.
