Robert Kubica has rubbished claims that he is driving “one-handed”, saying that would be impossible to do.

The Polish driver was back behind the wheel of a Formula 1 car in Abu Dhabi this week, taking part in a two-day test with Williams.

The outing is believed to be the final test as Williams evaluate both Kubica’s speed and limitations before deciding on their 2018 drive line-up.

And although Kubica set the team’s fastest time on Wednesday, he has been dogged by speculation about his limitations given the severe arm injury that he suffered in a rally crash in 2011.

The Pole, though, is adamant he is not racing one-handed.
