I think Vettel is being treated unfairly. People are saying he can't overtake. Maybe his overaking prowess isn't top notch ok, but to say "he can't overtake" is a gross exaggeration. Do remember that the RB7 is designed to do the fastest lap around a circuit a lot more so than other cars, and this brings compromises. Their kers definitely isn't on a par with the Macca and Ferrari, plus their 7th gear is always (most of the time?) geared short to yield better accelaration rather than top speed. These are good traits to have (correct me if I'm wrong) for setting the fastest quali lap and leading the race from the front, but most certainly a disadvantage when it comes to both attacking for on track position or defending. These traits I think hamper both Vettel and Webber when they have to tussle for position.
If you say "there were no cars around Vettel and he made an error on his own by putting his rear wheel on the grass and spinning thus ruining his race, much like he did in Canada by putting his rear wheel in the wrong place" then i'd say it's fair criticism.
