I have a 91 year old grandmother that still drives. Believe me when I say that she should not be driving anymore. BUT has only in the last year that her eyesite has failed. I whole heartedly feel that a vision, mental comptency and reflex testing should be mandatory every 2 years after 75 years of age. It should not cost more, if anything it should cost little to nothing. Have a heart they are elderly people, the majority of which are anything but wealthy.
