Did you actually look at the practice times? ... but don't qualify it with stats you haven't actually looked at.
Dude, you must stop being so emotional...you are doing your help absolutely no good whatsoever, by getting so wound up over a practise session.
First off, Vettel finished top of both sessions. Webber finished top in both sessions. As seen here:

We will not discount the first session (I take all sessions into consideration). Vettel finished half a second faster than anyone in FP1. In FP2, he finished 0.1s clear of the rest of the field. Now, if the this was Spa, Bahrain or any other long track, 0.1s would be nothing. However, this is Brazil - a short track which means that even a 0.1s advantage is something to be pleased with.
With regards to Webber having the fastest "ultimate lap time". I laughed out loud with that comment. Even Button could set a fastest "ultimate lap time". How would he do this? There are many ways to achieve this. The easiest method is described below:
Optimise your car (setup) for sector1 of the track. Go out and drive slowly on the sectors of the track which your car is not set up optimally for, but blitz the sector of the track your car is optimised for. Come back to the pits. You then set your car up so it performs best on sector2 (but performs poorly on the other sectors). Set a lap time. You then do the same for sector3.
Hey presto, all your lap times will now be slower than your rivals, but your "ultimate lap" will be the fastest, by quite a margin.
The point is that ultimate lap counts for nothing. The only thing which matters is the time you are able to produce using the same setup/tyres, throughout a single lap. The other factor is the ability to string together 3 good sectors. It is no good producing 2 stunning sectors and then making huge errors in the last sector.
Vettel has shown beyond doubt that he is considerably faster than Webber this season. Vettel's problem is that his car keeps breaking down, while leading. This has allowed Webber to maintain a lead (over Vettel) in the WDC, which by rights, he should not have.
We have also seen beyond doubt, that RBR IS the fastest car this year. This trend has continued in the 2 sessions we have seen in Brazil. (RBR finished top 2 in both sessions...this is a fact and I'm not quite sure if you are trying to dispute this).
We have also seen that in FP2, the 2 Ferrari's were able to jump up the time sheet. Alonso, as per usually slotted into the 3rd spot, behind Webber. In the race, it is quite possible that we shall see Webber fall apart and go backwards (just like we saw in the last race). My belief is that we shall see this happen and in the race, Vettel (who is the fastest car/driver package currently in F1), is likely to stay ahead of Alonso (just like we saw in the last race).
I didn't think that I would have to write up such a long post, simply to justify my assessment, but unfortunately deko asked for this.
Furthermore, BBC's Andrew Benson and Sarah Holt also agree with my assessment, regarding RBR's dominance in Brazil.
Red Bull have established themselves as the team to beat at the Brazilian Grand Prix by dominating practice on Friday.
