If the technology saves lives in a measurable way, then it should be used IMO. And yes, if my family member has 1/2 lower chance of dying in a car accident, I'll take it any day (I don't care if that lower chance comes from using AI or not).
If you are able to link actions of an individual to an injury in a jury-proof way, then sure I agree it should be done. It's likely not possible in most cases.
