Following the tragic events of September 11th neither of the Schumacher brothers is keen to race in the U.S. in two weeks time and Michael has commented to the German press that it is "unlikely" that he will be there. In what appears to be a heavy-handed move to prevent any disruption of his circus F1 boss Bernie Ecclestone has made some not too veiled threats that Michael Schumacher has not yet won this year’s Drivers’ Championship.
As Schumacher already has an unassailable points lead this must be inferring that he could be penalized some of those points if he does not go to the U.S. GP.
