Former World Champion Jacques Villeneuve says he still dreams of someday returning to Formula One racing. Villeneuve, who finished second in the Le Mans race this past weekend, said goodbye to Formula One in 2006 after having enjoyed spells behind the wheel for Williams, BAR, Renault, Sauber and BMW Sauber. According to the Canadian, the main reason he has not yet made a comeback is the lack of vacant race seats. "I'm open to the idea, certainly with the new technical situation," he told Autosprint. "To be honest, I have no idea if it would be possible. I have never given up hope to re-enter F1. I have driven in some other series, but that was only because there were no vacant seats in F1. "If the opportunity would occur, certainly with the new regulations, I would love to get back to work."
