How about driving on vacation through Utah last Summer and the Nav tells me to turn left while driving on a highway. The map shows a road to the left, but all there is are cattle grazing and not even a cow trail of a road ten miles either way.

Numerous people will tell you how TeleAtlas data frequently cannot identify the correct town for locations. I'm suspcious that it some how uses zip codes to identify town for locations, which is ridiculous, since there are many, many mailing addresses/zip codes that do not match the actual physical location.

But rather than type, just do a search and you will find many example of how bad Teleatlas data is.
