I re-watched the 2021 Abu Dhabi GP this morning while getting some time in on the stationary bike, and a particular event on Turn 9 stood out to me... looked really familiar.
Max runs Hamilton WAY wide, Max is barely on track himself let alone leaving room for Hamilton. Hamilton doesn't turn in, just runs through the corner to keep the place. Max complains that he needs the position back, no further investigation.
Checo runs Norris wide, but there's still room for at least 2 cars, one on track, one partially on the curb. Norris turns in on Checo and hits him, then turns and runs through the corner to keep the place. 5 second penalty.
One of these drivers got a penalty, and it's not the one who deserved it, imo.
I'm not trying to point fingers here at Max or anything like that, but when the rules aren't equally applied, it makes you scratch your head. The result of that call is Ferrari lost 2nd place in the championship, and Checo lost out on another podium.
