[_delirium]

Most of the elderly I know who don't have good enough eyesight to pass a driving exam can still walk around ok. My grandmother in Greece was able to do her own errands up until her 80s, for example, even though her eyesight was not good enough to drive. It wasn't a mile to the nearest supermarket, though; that might've been more difficult. In many cities you'll typically find a supermarket within a few blocks, if you live in the city. Here in Copenhagen, I would guess there's a supermarket every 1/4 mile on average.

I don't see many people out in wheelchairs either, and I agree accessibility for them could (and should) be improved. I do see quite a few people with walkers, though.
