Robert Kubica reveals he remains unable to drive single seater racing cars due to the "big limitation" of movement to his injured right arm.

The Pole, currently competing in Italy's Rally di Como in a WRC-winning Citroen C4, says he still has the desire to compete in "high-level championships in rally or on a circuit" while he continues his rehabilitation.

The former Renault and BMW-Sauber driver was badly injured in a rallying crash in Italy in February 2011, and says he has been focused on getting his "health and body back into the best condition" rather than keeping up his contacts in the world of Formula 1.
