How Old is Too Old To Hit the Road?

I came across this article in the New York Times's New Old Age Blog on the debate over senior citizens and whether or not they should be allowed to drive. While many people know that senior citizens are responsible for a good portion of vehicle accidents in America, I was unaware of the benefits that driving offers to elders. Driving not only acts as a form of transportation for them; it allows them to socialize, can lengthen life span, and prevent depression and institutionalization.

The author offered some interesting suggestions on how to prevent senior citizens from causing accidents by looking to British Columbia's prevention policies. In British Columbia, people over 80 have to present medical proof that they are fit to drive and are not allowed to drive at night.

I don't really know where I stand on this issue, because at 90 my grandmother still seemed alert and safe on the road. However, it is interesting to consider whether their should be an age limit for driving as there is one for obtaining your license.
