Robert Kubica has revealed that his physical limitations are still standing in the way of any hopes of a return to Formula 1.

The Pole, now 29, was regarded as one of the most talented drivers in Formula 1 ahead of his sixth season.

But in the 2011 pre-season, he was almost fatally wounded in a rally crash that has left him with only limited mobility in his right arm and hand.

Kubica now drives competitively in the world rally championship, and he has dabbled with circuit racing with a highly-competitive DTM test, and regular stints at the wheel of Mercedes’ sophisticated Formula 1 simulator.

But there are also things he can no longer do. Germany’s Welt newspaper reports that, once right-handed, Kubica has had to learn to write with his left hand since the crash.

He even prefers to drink a cup of coffee with his left hand nowadays.

“The limitations have made my life more difficult,” Kubica admitted.
