"Right now people aren't giving him many options,” lamented Tony Kanaan of Barrichello's prospects of staying in IndyCar. "They're asking him for money to keep racing in IndyCar, and he doesn't have all the sponsors. I know his heart is still in IndyCar, but he's not going to sit and wait.
"It's a shame, but it's the reality of racing right now. It's really sad. He has to look out for his own interest," Kanaan conceded.
If Barrichello does sign up for a full season in Brazilian Stock Cars he could still theoretically do a one-off guest appearance in IndyCar at next May's race on the streets of Sao Paulo, but a second Indianapolis 500 outing would be ruled out by a conflict with the fourth round of the stock car season.
Barrichello is said to be on the verge of revealing his plans in the next few days. "I think we will make an announcement soon," he told the Brazilian media at the weekend.
