And testing every older driver would cost millions more than most states have been willing to spend. One model may be Missouri. By not targeting older drivers, the law won support of the AARP and other groups.

Older drivers tend to show better judgment on the road.
For example, they are rarely arrested for drunken driving. And there is even evidence that senior drivers are better at regulating themselves than any government agency could be. They tend to avoid highways and limit trips to familiar and nearby places like the grocery store. 65 average a low 4,500 miles a year. The elderly who stop driving tend to become isolated and even depressed.
