Comment:

 Remember that all lines in geography are great circles, and that the
 further north you get the more a "horizontal" line in equirectangular
 projection will in fact arc northward, until in the limit it is going over
 the pole. This constantly trips people up applying "rectangular" boxes
 from flat mapping UIs to geography, and I do not see any way to "fix" it
 that does not do damage to peoples understanding in some other way. We
 just aren't use to reasoning about spherical geometry in general.
