This has a lot more application than just home addresses. Large parking lots, whole-in-the-wall diners in large cities, as mentioned before, out in the country because the address either doesn't exist or GPS, such as Google Maps has pinned that location 10 miles down a country road.
In my town, I live on the east end of the street, but the street doesn't have a west end. Its small but could be confusing to somebody that isn't familiar with my town. This would make it easier in my town as well when street addresses don't make sense because of poor town planning.
