Vettel
Before the start of 2010, I stated that Vettel is a top line driver and is in the same class as Alonso and Hamilton (who I believe are the top dogs in F1...Alonso with a very slight edge).
After he has won the title, my opinion of his driving ability has dropped slightly. One thing that is clear is that he doesn't have the ability to overtake in quite the same way as Hamilton or Alonso. Vettel needs to start at the front and have clean air to run. The moment he has someone ahead of him, he begins to fall apart.
The problem with the above trait is that when he has a car which isn't by far the best, he will struggle badly and is likely to fall behind even the likes of Webber (who I think is an average driver).
Apart from the problem of not being able to overtake, Vettel is the real deal. His problems will come when he does not have the best car.
The Turkish Incident
A lot of people dislike Vettel, after he crashed into Webber and then made out that it was Webber's fault by making the "mad hand gesture" as he walked back to the pits. I would've probably reacted similarly had I been told on the radio that Webber was not going to fight the overtake and that I should go for "it". I would've fully expected Webber to give me a wide berth and not cut back in to me after the nose of my car went ahead of his.
As far as I'm concerned, the crash was a racing accident, propagated by Webber's radio man not passing on the message for him to allow Vettel through. The other problem which didn't help was Horner repeatedly lying, which in turn put Vettel in a bad light. It was almost as if Webber was being unfairly treated, when in fact, he wasn't. Any No.2 driver can be asked to move aside. This is not unusual and has been happening for many decades. Perhaps some of the newer F1 fans are not aware of this.
The Future
Given that RBR have had one of the best cars for the last 2 years, it wouldn't surprise me if they have the best car in 2011 as well. McLaren and Ferrari really need to up their game.
2011
My pre-season prediction is Alonso for the title, simply because he is the daddy of F1 and this time around, he will be familiar with the inner workings of Ferrari. McLaren will shoot themselves in the foot again, as they refuse to enforce team orders right from the start of the season, allowing Button to take a few points away from Hamilton, in the first half of the season.
If RBR have the best car next year and enforce team orders right from the word go, Vettel will be unstoppable and RBR will win both titles with ease, next year. I'm hoping that, like this year, Webber is not forced to give way to Vettel, as I'd much rather see Hamilton or Alonso win the title and would love Webber to take points away from Vettel.
