"Results show that the average risk of severe injury for a pedestrian struck by a vehicle reaches 10% at an impact speed of 16 mph... The average risk of death for a pedestrian reaches 10% at an impact speed of 23 mph" [1] But, importantly, that's for human drivers, who are probably braking when, or at least after, the collision occurs. An AV that completely fails a detection wouldn't necessarily even try to stop.
