2 wins from 3 races, 1,2 in OZ, more than double the points of RBR, that's pretty dominant so far if you ask me (what if's aside)...Brawn has not dominated though thus far as far as i am concerned.
not sure they need it...If redbull opt for the diffuser vettel will be champion.
Again I would have to disagree with you, fastest laps by Button in Malaysia and fastest lap by Barri today, Rosberg in OZ, in qualifying P1,P2 in OZ, Button P1 in Malaysia, twice as many points as the next closest rival. Pretty dominant IMO...If you mean dominating on points then yes, if your talking about dominating in terms of being alot faster then no.
