Old Drivers

Is it just me or do I spend a large amount of time avoiding accident situations with old people. I can't be dreaming about these folks driving 15 mph on the highway, switching lanes without looking, stopping in the middle of the road and just driving in a generally bewildered state. It's almost the same kind of driving as if you put a goat behind the steering wheel. However, the goat never brags about their sterling driving record.
