It's of tremendous importance from the perspective of public perception of who's at fault.
If the average observer watching the published video arrives at a conclusion of "well I would have hit that person too, she appeared out of nowhere in front of the car", it obviously matters.
It does seem that there is a problem with the vehicle's lidar or the associated software, so does it not strike you as strange that the story being pushed claimed that the victim "came out of the shadows", which is a misleading irrelevance if lidar is the primary sensing technology? Especially as the unrealistically dark video does not even seem to fit that story.
