I understand that it would jeaprodize public safety, and that driving is a privelege rather than a right, but you still can't get by age discrimination. One argument I've heard is that a person's rights can only be exercised to the extent where they are not violating/limiting the enjoyment of someone else's. Even then, you would be taking a statistic and looking at a group of people not as individuals. I just think some arbitrary line in the sand would be discrimination. I'm totally in favor of the current laws, but how are they considered Constitutional?
