Nico Hulkenberg is without a seat for next season after Renault decided to hire Esteban Ocon in his place. Despite this, the German has said that he will be ready, should any opportunity come this way.
A return to Williams is also off the cards with Nicholas Latifi poised to replace Robert Kubica.
"Of course I've done mistakes as we all do sometimes that I would have liked to avoid, a few moves or things I'd do differently now, but that's always easy to say with hindsight," Hulkenberg told Autosport.com.
"So all-in-all, I'm at peace with what I've achieved and I don't feel I'm retiring as a race driver.
"I don't feel I am leaving F1, I might not be on the grid, but if there's an opportunity I'm going to be ready."
The German has collected 37 points so far this season, putting him 13th in the drivers' standings.
