Will you stop driving when you know when it is time?

Would you have done the same thing I did, if you were in my position? My mother had a brain tumor when she was 52. She had surgery and lived for 24 years. However, she had many small strokes. About 1 year after her surgery, she started driving her car again. She was in 2 wrecks (that were her fault). My great Aunt and 3 year old nephew were in the car. They had to use the jaws of life to get my aunt out of the car. Everybody was okay. Her decision making was not as good as it use to be. So she kept driving. My father would not stop her, because he didn’t want to hurt her feelings or take away her independence. I was afraid she would kill herself or someone else. First I called the DMV to see what they could do. They said there was nothing they could do, be cause it was her decision. So I called her insurance company, and told them what was going on. They immediately canceled her insurance, telling my parents it was because of the two accidents. My parents never knew I called. But my mother lived another happy 20 years. She was just fine with the fact that she could not drive anymore. I would imagine some people would not be fine.
