Not for 38 laps. Max did it six times after Horner told him to do so. Only then did the stewards step in and tell them to stop. So when LH does it, it's fine. If anyone else does it, it's bad.
Based on his 2020 record and the first race of 2021, Michael Masi is entirely in Mercedes pocket.
While you are entitled to your own opinion, you are not free to create your own facts.
At the driver meeting before the race, the drivers were told that corner 4 would not be monitored. Leclerc and others attest to that.
Red Bull realized that Hamilton (and others) were taking advantage of the lack of monitoring and going wide, Max was then asked to do the same (note that they did not complain but instead did the same, the radio evidence is very clear)
Red Bull decided to contact the race director about Turn 4 and only then did the race director change corner 4 from “unmonitored“ to “monitored” with warnings and penalties .
This was a rule change during the race which was not initiated by Merc but by RedBull.
While it is fair to blast Masi for not being consistent, the lack of consistency was not intended to please Merc but instead to appease those who complained (Red Bull). Listen to Hamilton’s reaction when told he needed to stop, he certainly did not sound pleased by Masi’s decision.
So much for Masi being ”entirely in Merc‘s pocket“.
The rules were the same for all drivers, some were smart enough to take advantage of them, others did not for whatever reason. Interesting that No driver has complained about what was happening at turn 4 before the change of rules, only fans who do not know the rules are complaining.
