Volvo's emergency braking system, which detected it and would have braked in time, had been restricted by Uber to not be able to take any action. Uber's system was set in a way that "non identified object in my way" didn't trigger an immediate slow down, but instead a "sleep it off for a second and check again". It saw the impact coming, and instead of notifying the driver it decided to wait a full second first, because it was programmed to do so. Which any programmer can recognize as the "turn it off and on again" idiom that tells us their system was misidentifying lots of things. What the driver did or did not do once notified doesn't change that. That car would have killed someone, somewhere, sometime, because it was programmed to not avoid it.
