CMV: Elderly people should have to take another driving test at a certain age

For the safety and well-being of all other drivers I think it makes sense to retest/reevaluate if an older aged individual is still capable of driving safely. 

I’m not sure at what age I would suggest the retest takes place, but I believe it should be done. 

My main point behind this is that it would make the roadways a safer place, not just for other drivers, but for older folks driving as well. 

In addition, I’d like to give ~~3~~ 4 personal anecdotes which explain my position:

1. Earlier this year I had a neighbor (in his late 70s) who was killed in a car accident where he pulled out in front of an 18 wheeler. His physical health had been deteriorating for a while now and although this could happen to anyone at any age I believe it to be a result of his age and physical decline.

2. My grandma has Alzheimer’s and in the earliest stages of it she ran a stop sign and t-boned another vehicle. I find it unlikely this would have happened had she been retested, because she probably wouldn’t have been declared fit to drive.

3. I was cut off while traveling 45MPH and tboned a car very violently. Both our cars were totaled and although I escaped with minor injuries, the driver (elderly) who cut me off suffered a few broken bones. Both the witnesses who pulled over and the police very quickly determined it was his fault. (Also he tried to sue me after wtf!)

4.  I got cut of today by an older gentleman and was about 2 feet away from slamming into his bumper had I not been paying attention, it would’ve been a pretty bad accident. 

This incident is what reminded me about how I think we could make the roads safer for all by reevaluating who in our elderly population is still fit to drive.

Why just elderly people? Why not make EVERYONE take a test periodically? Maybe every 10 years? That seems reasonable to me. It's very possible for a younger person to not drive for a long period of time and get out of practice. Or they can get used to bad driving habits which get ingrained, etc.

I think you run into too many problems with ageism if you say only old people have to take tests. Just say everyone has to take a test every 8-10 years, or so.
