Jolyon Palmer has said that Max Verstappen needs to "show more respect" on track after firmly pointing the finger at the Dutchman for their FP3 collision.
The duo collided at the final corner in the latter stages of FP3 with Palmer breaking his front wing and Verstappen picking up a puncture as a result of their small crash.
"His view is he is allowed to impede me, my view is it was silly for him to do that really," Palmer told Autosport. "It's just a respect thing really, to respect my fast lap.
"This weekend I've let many people past in the last corner. If you're not far enough ahead, let them go because they're on a quick lap. Then you start the lap behind them, they do their fast lap and get out the way so everyone can be happy.
"I'm not fussed he didn't get a penalty because it makes no difference. I just think we need to learn from it, show more respect."
Palmer also explained the incident in detail, saying that Verstappen should have ultimately got out of the way of him.
"I was on a quick lap, he was on a slow lap," Palmer added. "The slow driver should get out of the way.
"You're not allowed to impede on a fast lap, but he stayed on the line so I went on the inside and broke 20m early and took a lot of caution, but then he also took his apex which I didn't expect.
"If you're trying to prepare the lap, you're normally wide there anyway. I just don't really understand why he was on that part of the track.
"If you're preparing for a lap, no-one is ever on the off-camber bit on the inside. Everyone is getting right to the outside and getting the best drive possible."
"I think it was a silly incident and you don't want that sort of thing in FP3."
Palmer also said that his lock-up was a result of Verstappen catching him by surprise.
He said: "I think what contributed was Max turning in. Yeah, I locked up in the end, but only because he was turning in.
"The data shows I braked 20m early and was in control, and as soon as he starts turning into me I had to hit the brakes more and lock-up to avoid the crash."
