My parents have 2 cars. They both have damage to the rear bumpers because my dad refuses to use the backup camera. He hit a car in a parking lot and backed into the fence pulling out of the driveway. I saw this happen with my grandparents. Grandad was a perfect driver his whole life, then he had 3 accidents in a short period of time. The first 2 were minor fender benders. The last one was a head on collision that damn near killed both of them. Cognitive decline is a thing. Technology is your friend, and can help you prolong your useful time on earth.
Grandad eventually had his drivers license revoked because the 3 incidents in a short time period triggered a cognitive evaluation, and he failed the test. It’s sad to see my dad headed down the same road and stubbornly refuse to acknowledge it. If I am in a car with them, I am driving. Mom is fine, but patriarchal bullshit/stubborn pride leads my dad to insist on being the driver if it is just the two of them. He will probably have a serious accident sometime soon, and it will probably take that happening for him to admit that he’s in decline.
From a selfish perspective, if he would just use the fucking backup camera, my sister and I wouldn’t be having a conversation about dad’s driving. It would’ve probably bought him a couple of years of nobody noticing his driving is becoming a problem. From a practical perspective, maybe his stubborn ignorance is the canary in the coal mine. We’ve identified the problem before there are any real consequences, but unfortunately it’s going to take some consequences for him to acknowledge the problem. It’s not a fun thing to watch happen in real time.
