My grandmother hit and killed a highway worker when she was in her 80s. (She lived to be 100.) In her defense, there were extenuating circumstances, with him being shadowed by a big machine, not wearing an orange vest, she was driving into the sunset, etc. She did not get charged with anything. She had already just been driving to church in the next small town and nowhere else.

Sometime after that she had her cataracts repaired, but by then her judgment and memory had started to go. Instead of forcibly taking her driver's license and telling her she couldn't drive, there was just always something "wrong" with her car, and a willing grand-kid just "happening by" who might be able to take her to church. That she never suspected anything about the deception is telling about her state of mind. I think my family saved her dignity in this way. I hope my family is kind to me like that, when it's time.
