Although a collision may still have occurred if a human slammed on the brakes immediately after seeing the pedestrian, even a 10mph slowdown may have mitigated the fatality into a minor injury. ProPublica has a graph showing the frequency of fatalities in crashes for different impact speeds, showing a more than halving in the occurrence of fatalities in crashes between 38mph and 28mph impacts: https://www.propublica.org/article/unsafe-at-many-speeds https://www.propublica.org/article/unsafe-at-many-speeds The article says that the vehicle "doesn’t appear to slow down". If the data shows that it actually didn't slow down, it seems like there is a critical bug in Uber's software that has killed a pedestrian.
