The video released by Uber was extremely misleading. Here is a video on YouTube of the same stretch of road taken by someone with an ordinary phone camera shortly after Elaine’s death: https://www.youtube.com/watch?v=CRW0q8i3u6E
It’s clear that a) the road is well lit and b) visibility is far, far better than the Uber video would suggest.
An ordinary human driver would have seen Elaine & taken evasive action. This death is absolutely Uber’s responsibility.
