Just fyi you got autocorrected (I swear, autocorrect feels like it's more and more often these days changing from one correct word to a different word that's grammatically correct but not what I wanted to say) from "food" to "good".

Anyway, django's point was the same as OP's: that car-dependent urban design is bad for people. Food deserts are a feature of car dependency. They're not a necessary feature (as in, it is possible to have car-dependent cities that don't also have food desert), but by definition a 15-minute city, the thing this Community exists to advocate for, cannot be a food desert. A well-planned city makes it possible to get to a grocery store within a 15 minute walk or ride.
