FIA race director Michael Masi is to sternly remind the F1 drivers of their on-track "etiquette" after becoming annoyed by their actions at one stage during the Azerbaijan Grand Prix.
During the red-flag period following Max Verstappen's crash, McLaren team manager Paul James contacted Masi to question why AlphaTauri's Yuki Tsunoda had not been investigated for failing to slow behind the safety car.
A clearly angered Masi pointedly replied: "Quite simply, for me, the entire field should be penalised for not slowing for double yellows, in accordance with the regulations."
When James suggested to Masi that Tsunoda was an "obvious" call as the Japanese driver "hasn't lifted whatsoever", Masi retorted: "Paul, for me, all of them are obvious. Lifting a little bit for me is not enough and I'm going to tell all drivers accordingly at the next meeting."
Masi later reiterated the fact he will discuss the matter with all 20 drivers ahead of the customary meeting that takes place on a Friday prior to a grand prix weekend, with the next race in France on June 18-20.
Asked as to the meaning of 'not slowing down enough', Masi said: "The reason was, at that point, McLaren had asked a question about cars slowing for double-yellows.
"As I said on the radio, I'll have a discussion with all of the drivers at the next drivers' meeting about etiquette, let's call it, when double-waved yellow flags are displayed."
