McLaren's Jenson Button was critical of rival Pastor Maldonado after their incident during the Singapore Grand Prix, saying the Venezuelan "won't ever change" his "strange" driving.
Button lost part of his front wing after crashing into the back of Maldonado's Lotus while fighting for position near the end of the race.
The stewards investigated the incident, but deemed no further action was needed.
While Button said he did not believe he had been brake tested, the Briton felt Maldonado had been overly aggressive in their fight.
"I don't think he brake-tested me on the exit, but he didn't accelerate, so it was a bit of a surprise," said Button, who later retired from the race with car problems.
"It doesn't really matter anyway because we wouldn't have finished anyway.
"He was trying to block the inside line, so very strange.
"And the corner before that, he just drove me off the circuit. If there was a wall there I would have been in it. Very strange.
"He hasn't changed and he won't ever change."
