idk i feel like the grandma should have been more aware, i mean how can you go that long without learning the concept of look both ways. but at the same time i feel that the biker should have had enough distance to stop. responsibility lies on both ends i think.
Granny eyes are most likely **** , and motorcyclist did have enough time to move, he most likely moved but granny ran into him. So as long they are both okay it was a neutral accident
