To be honest, there should be road tests every 5 years for every driver. Maybe even a red flag law so family can request recertification. My grandma was on the road while being half blind. She would merge with zero knowledge of where any other cars were forcing them to take evasive maneuvers. We all kept telling her to stop driving but didn't have legal recourse until she was diagnosed with vision loss and dementia by her doctors at 85.

It's a miracle she didn't kill anyone. When I hit 70 I'm surrendering my license. Uber, e-bike and public transit for me.
