The Rundown...

Vettel: Well, as predicted on this blog - the only factor in his demise - is the car. But, as I thought further on the matter I realized some other factors woven into the entire story.
To Sebastian Vettel, independence is important to him as well as being in control of his own destiny. It's important for Seb to protect this independence by staying away from the corporate (read: controlling) nature of the larger teams because he fears total loss of his personality. Hence his choices to not play among the larger teams, to not have a manager and to stay with a team such as Red Bull which has the appearance of a team which supports independence. Is this just youthful rebellion or is he trying to blaze a trail to being able to maintain himself and win? But, I find that when you are dealing with an entity with something to hide, that entity then allows for independence in a more covert manner. "I'll let you be your way, without question, as long as you do the same for me." This is how the structure of corruption exists for it's participants. He's being controlled through a darker motivation and he's agreeing to give up a deeper sense of integrity.

Bottom line, Red Bull, as a non-manufacturer and its primary focus is to promote a drink product more than winning races. Red Bull cares less about winning and more in upping the sales of this dangerous beverage. I think the genius for Deitrich Mateschitz is his marketing plan, not his passion for racing. Compare this to a company like Ferrari, who clearly has a pure passion for racing and being the best automobile company on the planet. You see the contrast here...It's all about commitment and intention! This is simply why Red Bull cannot dynamically support racing at the level that Vettel wants to play.  For this reason, I don't see Red Bull taking the world championship this year or any year for that matter. I see Vettel faced with either his independence or becoming world champion. Next year, we may see Vettel at Ferrari or McLaren!

Hamilton: Will have to change his racing style to suit tire degradation - which includes less burnouts...LOL.
Lewis is busting out of the control his father has had over him. He's now more on his own and I think we can expect more things like this in the future..

Webber: So worried about losing races that he creates what he fears. As a result, constantly runs into other drivers. "If I can't win, you wont either." is his modus operandi. This is also why he's one of the hardest drivers to pass.  He doesn't know what motivates him on a deeper level.  He'll be out of a top-running car within 2 years... Maybe even next year.
