In my opinion, Sebastian is really pushing too hard...beyond his skill level really.  This crash should never have happened.  It really reminded me of the reckless crash that Vettel instigated in Turkey where he speared and took himself and his team mate out of the race...just dumb.  This really hurts Jenson Button chances...probably cost JB a sure second place finish.  Lewis summed it up this way:  

“I feel really sorry for Jenson, though. He did a great job. I got around Turn One, looked in my mirrors, saw him picking up places, and thought, ‘That’s good, that’s good.’ Then he got up to second, and I thought, ‘That’s fantastic – another opportunity for a one-two.’ Then, cruelly, he was taken out through no fault of his own – which was really unfortunate for him, and for the team, because he did everything he could to get us the most points in the constructors’ championship today. But he’ll bounce back even stronger. "

JB was not happy either, according to him "as everyone knows, I had an incident with Sebastian [Vettel]. I certainly didn’t brake any earlier than usual. All I know is I suddenly felt a big bang in the sidepod, which ripped the radiator out, and then I lost drive. I’ve watched it on TV now, and I’d say it was a very strange incident. Clearly, he didn’t do it on purpose, and I gather he’s now apologised, but I have to say I’ve got no idea what he was doing. It’s a massive blow to my world championship hopes."

I am not sure what can be done about Vettel as much of the pit wall were questioning his maturity after the most recent brainfart adds tio his resume of reckless crashed and bad decisions this year, he obviously need to take a deep breath.
