Am I the only one that thought his leg would snap in half when he jumped down off the car? Would've put a slightly sour note on his celebrations
As for the penalty, in live time I thought straight away that he'd get done. The front on camera angle of the cars coming down to turn 1 made it look like a pretty sharp movement, but the on-board doesn't look as aggressive. Now I'm only going by memory as I don't have the footage at hand, but I seem to remember Rubens was gathering Webber up pretty quickly and had the inside line, so I dare say the position was his as long as he held it into turn 1. When Webber hit him, you can see he (Rubens) slowed, so I can't agree that Webber hitting him cost Mark a place, as in my opinion he had all but lost it to Rubens already.
At the end of the day, penalty worthy or not, I think it was a bit of brain fade on Webber's part. He knew he was running longer than the Brawns and therefore had no reason to need to be in front of Rubens. Even when behind he managed to stay with him which was always going to be more than enough to jump him at the first round of stops.
