You can save the "line" and "alongside" nonsense for next season. He understeered into his opponent on the exit. Nothing else but poor driving. That is why Max apologized at Pia for it.
By his own poor driving, his fault. This is not the McLaren thread where you need to rotate reality and people need to defend poor driving all season long or need to pretend it did not happen. Just name it as what it is and move on.
It should be penalized like any other corner. Where do you take the reasoning from that the rules are different for this corner?
In contrast, drivers should take it more easy in T1. No one is helped if poor driving kills the rest of the race.
