My final paper

I decided to write my final paper on elderly driving. I have worked with a lot of elderly people because I worked in a long term care and rehab facility. I have dealt with every disease and sometimes they were just there to get strength back. So when they left guess what they would be doing? Driving home. Driving to the store. Driving to their children's house. It didn't matter where they were driving, a lot of them should have NEVER been allowed to sit in a car, let alone behind the steering wheel. They were confused and not all there sometimes.Their reflexes were horrible and the cognitive skills were off. Half the time they couldn't even follow a converstation or talk in full sentences. How the doctors allowed driving is a mystery to me. It was just scary to me seeing this. This was a big incentive to make it known how big of a problem it can be. We've all been around horrible elder drivers and I know you will agree with me that they should be taken off the road at a certain point. All im asking for is a test of some sort to test the capabilities of them. To make sure they are still capable of driving. If they pass well what did it really harm for them to prove it to society? And if they don't pass well then there is one less hazard out there on the road. Causing iritation to drivers or near accidents or just even driving SOOOO slow and in the way.
