Max Verstappen has come in for some criticism from his rival drivers following his defending against Ferrari's Kimi Raikkonen in Hungary.
The Red Bull driver held onto fifth place after keeping Raikkonen at bay for several laps. The Finn described the moves as "questionable" and complained over team radio on numerous occasions that Verstappen was moving more than once whilst in the braking zone.
Although Verstappen wasn't punished by the stewards, his rivals have also questioned whether that was correct.
Force India's Sergio Perez described some of the moves as "dangerous" and said he would raise the matter during the drivers' briefing on Friday evening.
"That was too much moving under braking. It's something we need to clarify," he told reporters in the Hockenheim paddock.
"We sometimes see drivers over-defending positions and it can be quite dangerous if you're moving under braking just in the last moment."
When asked if he would raise the matter with his fellow drivers, he replied: "Yes, we should talk about it, to clarify it. Moving on the brakes in the last moment was not correct."
McLaren's Jenson Button said such moves were a "no no" and reckons the stewards should consider penalising similar incidents in future.
"As drivers we all know that moving in the braking zone is the most dangerous thing you can do, because the [other] guy is at 300km/h and he probably hasn't hit the brakes yet," explained the 2009 world champion.
"Moving is a no no, and he obviously did move in the braking zones. I can understand Kimi's frustrations.
"The punishment is not important; it's important that we don't do it. The punishment is down to the FIA."
