Right. Yellow flags at Formula 1.
For briefings before the British GP, the FIA asks us to restrict the use of Yellows in Qualifying, and to only put them out if essential.
So if there is a car just running wide or rejoining on the grass, it doesn't need a yellow like it would in the race or practice.
However, yellows can still be displayed if there is a crash or something that the drivers absolutely need to know about. A spinner stopped on the racing line, a large chunk of debris in a bad place, a car in the wall, a car stopped on track.
In this case, there was a car stopped on track. That needs a yellow flag. If Max had lost it on the exit kerb and smashed into Gasly's car and there weren't yellows, the fallout would be monumental because "uh you didn't warn us". There was the Alonso clarification that a lap with yellow flags wouldn't count after Turkey, so why did the drivers keep going when they saw the flags? Why did they NOT see the flags? Do they not know the rules?
BStian Horner is allowed to defend his driver, but you have to be realistic and accept that they aren't right all the time. Blaming a "rogue marshal" is complete 💩 . They are out there to look for stuff the drivers need to avoid, and it doesn't matter what the situation and session is, if there's a flapping bit of yellow cloth - slow the F down or accept the consequences. Slam dunk is slam dunk and BStian needs to shut up and accept it sometimes all the time.
