Renault's Cyril Abiteboul isn't committing Renault to providing Robert Kubica with further testing opportunities until the Pole clearly decides the path to his future.
Kubica was satisfied with the outcome of his test at Valencia last week which saw the former Renault driver get behind the wheel of an F1 car for the first time since a rally accident in 2011 halted his career at the pinnacle of motorsport.
"He did the test because he wanted to," Abiteboul told French broadcaster Canal Plus.
"The Enstone family is very loyal: people like Alan Permane, Bob Bell, Nick Chester, everyone wanted to give their driver the opportunity to drive.
"The opportunity came when we had a day scheduled (at Valencia) with Sergey Sirotkin," Abiteboul explained.
Abiteboul isn't projecting Kubica's immediate future however.
"There is no idea and I do not want to get into a pressure situation," he insisted.
"Robert is measuring his skills and his limits, and once he knows his limits, he can make a decision for the rest of his career."
Renault engineering chief Alan Permane said the team tried its best to keep Kubica's test low-profile.
"Robert has a lot of fans upset that he is not in formula one, so we did not want to put this additional pressure on him, although he could have dealt with it," he said.
"I just wanted Robert to enjoy it.
"Of course, there is no limit to perfection, but Robert was physically well prepared. We had to move a few switches to the other side (of the steering wheel) so he could use them, but there was nothing difficult."
As for the next steps, Permane said: "It's too early to talk about it, but we are in touch with Robert. There are no plans to continue the tests, but it is possible for the future."
