I would have to say Robert Kubica. In my opinion, he’s much like Mark Webber in that Kubica was never in a legitimate winning team (i.e. Ferrari, McLaren, Red Bull, Mercedes, or the current Louts). During Kubica’s time at BMW Sauber, the only real race winning car that was given to him was in 2008 in which he won the Canadian Grand Prix (with his then teammate Nick Heidfeld coming in 2nd). Other than in 2008, he has not been given a car to win in. He has demonstrated speed, however, even more recently in 2010. His three podiums in Australia, Monaco, and Spa were brilliant drives. Who knows, if he was never involved in that horrific rally crash in the winter of 2011, he might be at Ferrari, McLaren, or even have stayed at Lotus (which is now a race winning team). The mere thought of Raikkonen and Kubica is a fantastic driver lineup!
