Rubens Barrichello says he has been assured he will not go into the winter without any news from Williams on his future with the team.
The veteran Brazilian is still hoping to secure a new deal with the squad, although Williams is set to wait to decide on its line-up for the 2012 season.
Barrichello has made it clear he will do whatever it takes to be racing in Formula 1 next year, and says he has been told by Williams that he at least will not be kept waiting going into the winter.
"I hope before Brazil we know," said Barrichello. "The fans need to know. Williams told me they would like to make a decision before Brazil, so I hope at least that is a positive. I would like that to happen."
Barrichello admitted Renault would also be a possibility for him if there was a seat available.
But the Brazilian insists he does not want to be in Formula 1 without a competitive car.
"For sure. I think that there are two or three opportunities that are quite good," he said. "I would not drive in F1 for anything, just for the sake of saying, 'oh yes I completed 20 years now even though I don't have a competitive car'.
"That is not the question. The teams I am talking to have the qualities to build a good car and perform."
He added: "If my destiny tells me that it is not for me to be involved in F1 then I had a wonderful 19 years. I am going to try and think of something and see if they want me to drive the Disney cars at Disneyworld!
"I've had a wonderful time. All I want to say is that I belong here, and I have never been as quick as I am right now and I want to be driving next year. But if destiny turns it into a way that is not for me, then I will be home."
