Last year, some low down team did the same. They got penalised VERY heavily, if I remember correctly. Also, Massa pulled out right in front of that Force India. If they don't get penalised, than F1 is definately biased towards Ferrari. Simple as that. Also, the FIA will hopefully ban the green light release system that is causing these problems!
Massa must get a penalty for the unsafe release this time. Ferrari have to get rid of the semi-auto system. Unless something disastrous happens to Hamilton here (retirement or crash) the championship is going very much towards Hamilton.
edit: Sutil did the same thing (drove off the down the pitlane with the hose attached) at France last year.
