I don't mind it when authors get details wrong in cities I'm familiar with--Google Maps and streetview notwithstanding--because most of them are by definition set in alternate universes.
In fact, the case can be made that all fiction takes place in alternate universes. So if the author has the White House painted pink or puts traffic circles where they don't exist... well, obviously things happened a wee bit differently in that timeline.
Of course, if the story sucks, *then* I'll be offended at their sloppy research...
