It was thoughBut it wasn't clearly broken.
Track positionWhat advantage did Norris gain?
He was in the middle of an overtake attempt at the end of the straight, nothing more.He was ahead of Max at the end of the straight.
Max didn't get the place 'back', or even keep the place, he lost the place - that's why Norris was in front of him after the corner. Maybe this is why you are confused - you realise Norris was ahead of Max after this encounter yes?Max only got the place back because he braked late, went off the track and drove Norris wide.
Had any number of other hypothetical scenarios occurred, then any number of other hypothetical outcomes would no doubt be true, yes.Had he been sporting and not done that, Norris would have no doubt kept ahead after the corner.
As it was, Norris attempted the overtake, Max pushed them both off as he likes to do and this meant when re-joining at least one of them was going to be (or at least should be) guilty of 'gaining a lasting advantage' from going off track as per regulation 33.3. Norris chose to complete the overtake and make it himself that was guilty. He could have re-joined behind Max and it would have been Max that was guilty of the infringement instead.
I don't like it, you don't like it, virtually nobody actually likes it but lets not deny the reality of what occurred so we can try and kid ourselves that Max should have received a penalty in this scenario. It would be nice if the rules meant that when the defending car barrels off the track trying to defend, then the attacking car is immune from being considered to take advantage of the combined excursion to the run off area but that's not what the rules currently are, so we are where we are - Norris is the only one of them to infringe on an actual regulation, so he's the only one that got pinged with a punishment.
