Toyota and Williams both had double diffusers from the start of the season...
bingo. 3 teams with clever designers, after all f1 should be about innovation
exactly... thats what the constructors championship is all about isn't it? they are all given the same rules... its just a matter of interpretation.
however... if all the cars were exactly the same it would be very dull and the constructors championship pointless
anyway... well done Jenson and Brawn
