NYS has a means to have a driver re-evaluated.

It's a problem around here, always an elderly person with a terrified look on their face as its pressed against the windshield with a terrified look on their face while they are driving 20 MPH under the posted speed and there's a dozen or more cars trailing behind them. You cannot deny that based on what is easily seen on a daily basis. Lot of retirement residences now where crops were grown, people live longer and a fair amount of them may need to be re-evaluated. Not always an elderly person either, but most often it is.
My mother is one of them, she's accident prone and does not have good ability to back up, I have to park the vehicle in the garage daily. She won't give it up until something drastic happens, there is no doubt being as stubborn as she is, same with cigarettes, people just don't want to make changes even if its for the safety of themselves, and more importantly, the safety of others whom have no idea of the ability of who they share the roads with.
I have a 94 year old relative, who drives fine, but I have seen him with a trail of cars behind him too as I recall.
Thankfully, you can recommend that a person get re-evaluated here in NY.
I had an experience with one while driving a tractor trailer years ago, when I was 21, or 22. Elderly driver tried to turn in the same direction as I was on the inside, and the truss trailer hooked onto his car. It felt like a brake was hanging up, I was up shifting the R model Mack with a 300+ and 9 speed transmission. By the time I looked back, the car was pulled into the curb, breaking or bending the wheels off one side and it popped all the windows out of it. The driver was ok, but could not explain why he did what he did. The law decided it was my fault and I received points on my license, which was completely wrong. I had my turn signal on and was making a 100% legal turn. Old guy said, well at least I am getting a new car out of the deal !
People need to know when to give it up, but they just don't sometimes. All of us will be there someday.
