The latest regarding the self driving death in Arizona

The lady pushing the bicycle while it was dark in Arizona has been ruled? that neither a driver nor a self driving vehicle could see the woman as she crossed in the dark where there was no crosswalk. So, since an actual driver or a self driving vehicle camera could not even see her clearly and since she didn't use a cross walk, Uber is likely not at fault here but instead the lady with the bicycle crossing when no one could see her somewhere there was no crosswalk. Also, she wasn't riding the bicycle she was pushing it while walking as well.
