I can only speak for myself but I believe some others may feel the same, when I say I cannot see someone ejected, I mean with no impact with something, rollover, etc. In the case you cited, a tree was hit/there was an impact. In this case, we are told of an accident but no other car, tree, etc. We are led to believe she was in the water and got out of the water, to the road, not ejected on hitting a tree on the way down.
I agree totally if there was an impact, someone could be ejected.
Again, just speaking for myself.
