I get WHY it's an issue. However, in the actual patent application, Microsoft never specifically calls a GPS feature that's designed to guide drivers away from high crime areas (and bad weather) an "Avoid Ghetto" option.
So, the quotation marks "journalists" have been using in most of the stories on this are somewhat questionable. I'm not sure exactly who they're quoting. Maybe each other.
Also, something buried in the patent application and NOT getting much attention is a GPS feature that monetizes redirecting drivers in order to get them to buy stuff:
"Moreover, a reward operation can take place in relation to user response to a commercial detail (e.g., presented with a pedestrian route). For example, an advertisement can be played that a user should stop at a highway exit for a cup of coffee. If the user takes the exit, buys the cup of coffee, buys a different item, etc., then payments of varying amounts can be made to an advertisement hosting service."
