MONZA, Italy - Robert Kubica is still hoping to return to Formula 1, a year and a half after the near-fatal rally accident.The former Renault driver, now out of contract after missing all of last season following his crash in February 2011 and enduring repeated surgery, told Sky Italia that he had unfinished business.Kubica participated in the Rally Ronde Gomitolo di Lana event during the same weekend of the 2012 Italian Grand Prix.RETURNING TO F1Kubica said: "Being here is already a good step, but I would have preferred to be somewhere else."I have still got a long road to travel and will probably never be at the same physical level as before. But I don't intend to give up."The aim remains to return to Formula One and the next few months will tell me whether I can do it next year already or will have to wait until 2014," he said.Kubica, who suffered severe arm and leg injuries in the 2011 accident, was a race winner with BMW-Sauber and Renault's lead driver. He had been linked to Ferrari before the crash as a possible replacement for Felipe Massa.Fernando Alonso, Ferrari's championship leader, is one of his best friends in the Formula 1 paddock.Renault team boss Eric Boullier said that his team now had little contact with Kubica.Boullier said: "I did read in the press, like you, that he was doing some rallying and actually he's supposed to do a rally next weekend or something like this, but we don't have much contact."I have contact with his management but nothing else. I've not been updated about his current state for a long time."
