the race control officials were way too slack for the first race i reackon....specially Barrichello should have been penalised for hitting Webber on the side on the first turn...first lap...i mean that was such an avoidable accident but guess what Rubens just barged his way through recklessly...Very very bad luck for both vettel and kubica they should have just been happy with where they were at for the first race....
And luke a lot of drivers did user KERS on the start....Kubica chose not to have KERS on his car...30Kg less weight...goes to show that you dont really need KERS but seen it work and it definately helps in passing or defending
