If there was no malicious intent that can be proved. Then there isn't anything for the police to investigate.
Do you report all the little incidents that occur while you are driving that could have killed or maimed you?
Perhaps the video might be useful to a cycling advocacy group to use as a example that such things do happen. I actually got rear ended in my truck while stopping to allow a cyclist I'd just passed on a sidewalk to cross the entrance to a parking lot. I think the cyclist must have slowed down thinking I was going to do a right turn in front of them. Because they slowed down, I had to stop. Then bang.... tore up the front end of the car hitting me. Nothing for my old beat up truck.
