Jolyon Palmer has dismissed claims that he might take too "cautious" an approach to his job of being a Formula 1 driver.

Last year, the British rookie was Lotus's reserve and Friday driver, and was signed up to race for 2016 before Renault took over the struggling Enstone team.

However, even Lotus admitted to having some doubts about the 25-year-old, as trackside chief Alan Permane went on the record to question Palmer's aggression during his numerous outings in Friday morning practice sessions.

"He told me that personally, so I wasn't particularly surprised when I saw the interview," Palmer told the March edition of F1 Racing magazine.

"He had a point, but when you drive a car in FP1, it's not perfectly designed for you and if you crash, then you ruin your teammate's weekend. You can't really drive flat-out; if you do and crash, you're a villain.

"It will be very different when I have my own car to race."

The 2016 season begins on March 20 with the Australian Grand Prix.
