Felipe Massa has been disqualified from the Brazilian GP as a result of too high temperature in his tyres before the start of the race. Unlike Lewis Hamilton who's tyres were BELOW the required minimum PSI to start the race in Italy, and who was not penalised. Hamilton got away with it and it seems to me like harking back to the days of when Schumacher got away with everything but no one else did.

I would also imagine that the race stewards will have needed heavy disguises to get out of Interlagos alive.
