F1 return 'nearly impossible' - Kubica
Robert Kubica has admitted a return to Formula One is "nearly impossible" at the moment and that he is focusing his attention on rallying.
Kubica is still recovering from a rally accident in 2011 that partially severed his right hand and forced him to put his F1 career on hold. He has returned to rallying this year, winning the WRC2 category and lining himself up for a WRC drive at this weekend's Wales Rally GB.
However, when asked by BBC Sport if he could make a return to F1, Kubica said he would still be severely limited.
"I would be able to drive an F1 car on one or two circuits for testing. But it doesn't make sense to test for a day if I cannot race."
He added that he would not return unless he felt completely ready and admitted that was unlikely.
"I think there is only one person who can judge what I can do behind the steering wheel - and that's myself," he said. "It's a dream, a target, but for now, it's very difficult - I would say nearly impossible. I will never take the opportunity if I don't feel 100% ready. If one day things improve, for sure we will see. For now, I am concentrating on rallying."
Kubica will drive a full-blooded Citroen DS3 WRC car at this weekend's Wales Rally GB, but said his hand is still not up to the challenge of driving a Formula One car.
"I focus on my recovery - and rallying is helping me a lot in this," he added. "I can see a lot of improvement behind the wheel in a rally car. Driving on gravel is very demanding. There are lots of movements on the steering wheel which put a lot of stress on my arm and my hand.
"But I know this does not help my biggest limitation, which is driving a single-seater. I do not have the power to take control of it but I will try my best."
