My own GPS trace confirmed the contributed traces so I have set up an Imagery Offset for Bing at this junction in JOSM. I've also nudged a large number of nearby buildings to align with it, and a small number of streets nudged in the opposite direction. At least now, the streets and the buildings mostly align. But I've probably missed some of them. So will be rechecking. Feel free to move any I've missed and start on those further afield :)
