For an unrelated product demo some years ago I modded Orbital Eunuchs Sniper¹ to play on the environment outside the site we were demoing in using a few images from Google Maps. The split on whether it was fun or utterly wrong was probably 90/10, but I'm sure it would've been a different story with a tabloid paper reporting on it.

Now imagine you're publishing a game where drifting on roundabouts outside real elementary schools is a mini-game. Probably good for publicity though, iff you're willing to take the heat :/
