The cars are only illegal if the FIA say so and if their tests havent been able to find a problem, then that means Redbull (adrian newey) has just been smarter than the rest.
Same happened in 2009 with the brawn and couple of other cars...
I hope next years rule changes spice things up a little, but it rarely seems to make a massive change in the order we see. With any luck it will rein red bull back in a bit.
As for the drivers, to say vettel isnt a good driver is just plain BS, in fairness to the lad he's rarely needed to overtake because he's always at the front, hes just out of practise
I think hamilton has smashed a mirror or walked under a ladder or something because this year has just been horrible to watch for him. i hope he can get it back together for next year, because in my opinion he is the quicker driver out of him and button. Thats not to say button isnt good, i just dont think hes as quick as your Vettels and hamiltons of the world. the thing that really annoys me about him, you really need to keep him in a good mood, when he gets down in the dumps about something, he seems to stay in a rut for while until things go his way. Just look at the middle part of the season in 2009, he wasnt getting results like barrichelo was and in my opinion he scraped it.
