About every 3 weeks or so there is a picture in the newspaper of a car in a swimming pool or inside a 7/11 store usually driven by a senior citizen who just got the pedals wrong that day. None seem to be the result of sudden incapacitation. I bet if you asked each one of these drivers a few minutes before their mishaps if they have any problems with age and driving, they'd probably tell you to #$% off, and that they are ok to drive.
You are comparing apples to oranges. You cannot compare the pilot work force with every other option and range of health and motor skills. Even if you could compare the two groups the only ones that would count among the crashed car brigade are the ones under seventy.
