If I pinch to zoom to a scale that makes sense to me (eg include Perth and Geraldton on one screen on my iPhone) and then pan around the globe to Europe, the scale becomes three times larger.
This is not helpful if I’m trying to set my travel expectations for holiday planning!
I understand this is necessary on a sheet of paper, but I can’t see an excuse for it digitally. Let a kilometre be a kilometre wherever I am looking!
