Right. I mean it's basically that the distance here is defined quite strictly when it really depends on the individual. I could be 200km from the nearest groce

Right. I mean it's basically that the distance here is defined quite strictly when it really depends on the individual. I could be 200km from the nearest grocery store, and it'd just mean I need to stockpile a bit more, because as you say, assuming there are roads etc, I can jump in the car whenever and go there. By contrast someone who's poor and severely disabled might feel they're in a 'desert' if the nearest store is 200m away and they can't walk.
