In some places, nobody uses those CDP names, and they really shouldn't be on the map, but they're still going to show the error bubbles if you remove them.
Forget Zip Code maps. The USPS has consolidated so many towns and small cities into the nearest large city, they'll be useless.
Most of these that I've seen were caused by people adding city names outside of the city limits, where the No City box should be checked.

The reason for the city layer is to have accurate polygons to the city limits or edges of the CDPs.

If "accurate polygons" is the only reason to update city information and they are not used for anything practical in Waze, why have them and why should any one bother updating city information or putting correct information in it all? ever? And why does Waze care?
