Guys, without the time to read all the stuff above, I like to throw in my general thoughts about that area of the track.
The special situation of this area is the kink after and before the straight. So in comparison to an easy straight, it is not easy for the chased driver to show where he intends to go
before and through the kink. So missunderstandings or missinterpretations can easily happen!
So if the chasing driver is in doubt where the chased driver wants to place his car on the straight after the kink, he should settle behind (maybe by lifting) and make his move after the kink. That shouldn't be hard as he has enough time to benefit from the slip stream even after the kink(?).
Of course if the chasing driver made it in a predictable position already before the kink, it should be clear for the chased one wether he must take a tight or wide line through the kink. But if the chasing driver "arrives" when going through the kink, I think he can't expect the driver in front might asume which side he wants to take.
Why not go tight there whenever we are in front of a car. Predictability and no significant loss of speed.
I think it's not fair to generally enforce the driver in front where to go. In my opinion the driver in front has always the free choice how to defend and the following driver has to react properly.
To sum my thoughts up: If the chasing driver wants to go besides another driver when going through a corner (here it's a kink), then it should be his responsibility to make it safe for both of them, otherwise he should wait until the next straight when the driver in front could show where he wants to hold the line.
