a go-nogo app that pulls publicly available information like demographics, income levels, crime statistics, section-8 housing, HUD data, free lunch participation (school zones), etc as well as obvious giveaways like "MLK blvd" into a google map layer much like traffic congestion is currently displayed that lets you know what areas to avoid when not only driving (main feature) but also just displays the info so you know where to move/rent/etc in cities.
To stay "on the right side of history" and not get cancelled, it will be marketed extensively as a woke-fest "anti-colonialism, anti-gentrification" app so black folk can avoid hipster whitey's attempt at forcing them out of neighborhoods by introducing civilization which raises their rent to the point they can no longer afford them, allowing them to "stay 100" and self-isolate/self-segregate within their own urban communities. The default view will show rich urban areas of cultural significance to the black community and all the places where black people can feel "safe."
Obviously it will have a "reverse" button which is really the default mode so civilized people of all colors can avoid no-go zones and plot driving routes to down town areas like the stadium without worrying about getting car jacked or murdered.
