Actually I think it’s great you posted this and included a comprehensive replay so thank you.
Here is a summary of the FIA rule that applies in this situation.
So the question is how much of your car you got alongside his - if you
Overlapped his axle at the apex, blame is shared, less blame is yours.
In this case, the attacker’s front axle is ahead of the defender’s rear axle and the two cars are approximately halfway alongside. Both drivers have a reasonable claim to the apex. If contact occurs, blame will have to be shared. It is in this zone that
racing incidents can occur. Ayrton Senna was famous for creating situations just like this, as both attacker and defender, where the other driver would have to decide whether or not to yield to avoid a collision.
This is copied from the following link which is a nice summary of the FIA rules.
