Robert Kubica vented his frustrations with and to the media for its incessant questions about his relative physical limitations with regard to driving an F1 car.
The Pole suffers from reduced mobility and strength in his right wrist and hand following his severe rally crash in 2011 which also forced him out of F1 at a promising stage of his career.
Last year, Kubica gradually put himself back in contention for a seat, undertaking evaluation tests with Renault and Williams, and ultimately landing a reserve driver role with the Grove-based outfit.
Following a 58-lap run with the team's FW41 yesterday afternoon, the 33-year-old was once again questioned about his physical ability, but also made clear that the time had come to put the subject to rest.
"I have always been comfortable, it was only media talks that I was not comfortable," he said.
"If I keep changing things you will keep saying I have limitations. We should stop talking about this.
"If I can jump in the car and do the job I think that's fair enough, of course I have my limitations but I never hide them."
In hindsight, Kubica believes he was perhaps too forthcoming when explaining his issues.
"The problem is I was too honest with everybody and they kept asking questions, I think we should stop it," he added.
"We have things to concentrate on. I’m living a good experience, I’m enjoying my role. I’m happy to give positive messages, not always the same story after many years."
