Kubica would be 'disappointed' if there is no 2018 return

Robert Kubica has confessed that he would be 'disappointed' if his efforts in test races with Williams do not lead to a return to the sport for the 2018 season, and has insisted that he is arguably better suited to racing now even after the accident which nearly cost him his career.

Kubica was with BMW and then Renault from 2006 to 2010, and became the first Pole to win a Grand Prix when he took the flag at the Canadian GP in 2008. A promising career was halted when he lost part of his arm following an accident during a rally race, but is now testing with Williams in Abu Dhabi this week in the hopes of claiming a full-time contract for the 2018 campaign.

He does not want to return just for the sake of it, but would be disappointed if an offer didn't come in.

"It's not that I want to come back just to come back," he said.

"Even if I will get a chance and don't feel confident or able to do it I will not come back, there is no point.

"I'm very demanding of myself and although I understand my situation and try to adapt, in the end the high standards I put into what I'm doing, it hasn't changed. The worst thing I would do is convince myself that I can do it and then having troubles.

"There are question marks have to be answered for the team and also myself.

"But this day, in generally I see big improvements, day by day, so I can expect things getting better which is why I say I would be disappointed [if nothing further happened].

"Because in the end I put in a lot of effort and I see there is a good chance I am able to do it."

There have been some figures within the sport who have not supported a comeback for Kubica as it would be a risk for other drivers on the track, but Kubica himself has claimed he is arguably in better shape than he was when he was competing previously, even if there is lots more to learn as F1 has evolved so much.

"There is someone saying I'm driving one-handed, but for sure I think it's impossible to drive an F1 car with one hand," he said.

"For sure I have some limitations, so in some way I am using some [of] my body [to] learn some compensations, which is natural.

"That's something which I think I'm on top of it, and physically I think I have done great work, good work in last six months.

"It hasn't been easy, it's not like I've been lying in bed, actually probably I'm in physically [the] best shape by far, better shape than when I was racing in 2010.

"The motivation is there, the body is reacting in a good way, of course I'm starting from nearly scratch as Formula 1 has changed so much in last seven years that it's likely nearly starting from zero.

"But the experience I gain from the years I was racing in Formula 1 will help me to get on top of the learning process quicker than it used to be in the past."
