You can't get a drivers license if your vision falls below 20/40. That's a "slight hint of incapacitation".

Edit to clarify: ...without also requiring eye correction. Of course you can wear glasses to drive, but it becomes mandatory, and without that eye correction you cannot get a license.

Try and suggest to people over the age of 70 that they need to take more frequent drivers tests or get certified by their doctor to safely operate a vehicle.

You'll learn quickly that cognitive dissonance is a real thing.

California allows for another person to contact the DMV to suggest that a person of any age needs a reexamination. [0]

Good thing people don't need a gun to get to work every day, otherwise we'd see lots of cognitive dissonance there too.
