Oh believe me I read the second scenario several times. For the first one it's "blatantly obvious" that you should just stop overtaking if someone is being hostile against you. Even if you have a rally cross situation behind you, the physics works out to be safer if you abort. Second one is rather confusing, but it would appear that this driver of D having realized intentions of C decided to brute force the situation with speed, making driver of A to solve everything again with even more speed. This mentality of speeding just ends up amplifying until something gives.
