I can comment on IMPAIRED DRIVERS. I chose to give up my license due to Macular. I had lost vision in the center of one eye and was 70/20. When I went to give up my license I was told "Oh you can get a license in Florida at 70/20", I told her "Believe me, you do not want me on the road", but legally I could be out there driving. I no longer drive a car or a golf cart, if I had an accident Dan Newlin could get everything I own.
THE STATE OF FLORIDA DOES NOT WANT TO UPSET ITS ELDERLY POPULATION.
One of my neighbors lost sight in one eye and was driving from PA every year with just one eye!, and that too is legal in Florida. To take it even further, what about all the early dementia patients here!
