According to Joe Saward he thinks its all down to Malaysia and doesn't seem impressed at Vettel attacking the crowd over booing him.
I personally think Vettel has handled it well as it can't be nice whatever the reason.
A few things:
1. Joe Saward is a moron. He uses his blog as an attacking tool against drivers who are not of his liking, but he doesn't allow second opinions on the subject. He is so insecure of himself that, more than once, he has ended up closing comments on his blog, deleting post, or simply attacking its users.
2. Malaysia? Really? The whole problem with Malaysia is that it was Vettel who did it. Had it been the other way around (Webber attacking,Vettel and passing him) we would be talking about it as "good Webber for the Sport, team orders suck! Racers should be allowed to race, not asked to protect their teammates" etc, etc.
3. Attacking the fans? He made what was clearly a joke (the travelling around, very wealthy european fans comment), and he seems to doesn't care. He will continue to win (probably even more than 4 titles, no matter how bad that pisses off people like Mr. Saward) and he will continue to have a healthy sleep at night despite the boos of a handful.
4. The really hypocritical thing with this is how the press was ignoring the issue until it became "a fashion" (i.e. you boo vettel in the podium, regardless of...) and now are coming with make-up excuses. Vettel was winning, Hamilton and Alonso were not. The press has been overselling the point about "it is all his car, not him" to the point a lot of average joes who go to races have bought it, and don't celebrate an "average" driver winning with the "awesome" car (however, how many P2 in the WDC has Webber got with the same car?). What the press has not been able to admit is that Vettel hasn't had the best car by a mile for a generous chunk of this season (or last season for that matter), yet he is the one currently on top; and when he had the amazing car (2011) he dominated to above Schumacher standards (and yet, where did Webber finished that season?). If the media were to take its real position, and present how ridiculously good the kid is, the whole point of "it is only the car, let's boo him" will start to fade away.
