Robert Kubica believes he may return to the Formula 1 grid in the future, but accepts he has "no control" over whether another chance will present itself.
The 35-year-old grand prix winner made his full-time return to F1 this year as part of the struggling Williams outfit and scored the team's only point of 2019, despite being out-qualified by George Russell at every race weekend.
Kubica announced he would be leaving the team towards the end of the season and will be replaced by Formula 2 racer Nicholas Latifi.
But though Kubica admits there is "realistically a big chance" that this month's Abu Dhabi Grand Prix was his final F1 race, he says he will have an outside hope of a comeback as long as he retains an F1 paddock presence.
"You never know in your life," Kubica said. "Of course, if in the future I will not be in the paddock, there is [a] very slim chance [of racing in F1 again].

- Why it went wrong
"If I will be in the paddock, then everything might happen. I'm keeping my feet on the ground and realistically there's a much higher chance that this was the last race than [that] I will race again.
"This is a realistic overview."
Kubica said that the earlier experience of having had a promising F1 career diverted by his severe rally crash in 2011 taught him that he has little influence over the way his F1 future will pan out.
"I have no control over it - there might be a chance [of a comeback], there might not be," he said. "I think in the last 10 years I learned a big lesson.
"Even when everything is [seemingly] under control in your life - in the past I had a contract for another three years of racing and I ended up in hospital with half of my body damaged and I nearly lost my life.
"Hopefully this time it will be different."
