Whilst you're correct that the higher the speed the more likely a fatality, it's also possible to cause death at very low speeds.

My wife was involved in a similar accident except the victim was an elderly lady. My wife was driving very carefully, not speeding etc.

One of the things that I observed whilst we endured the aftermath is the lack of support for people in this situation and what a taboo there is around it. It felt as if there was no 'right' to sympathy or support due to the asymmetry of experience for those involved. It's even difficult to find the right language without it being pejorative. 'Hit and killed' implies some kind of intent or that there was some kind of choice.
