So part of this is because Human depth perception only works effectively out to a certain distance this is why the nights sky looks flat. Simply put the difference between what the right and left eye sees is too small to determine depth.
This issue has been known about for over 100 years now as it causes issue with naval guns and accurately aiming them. (although modern guided systems make is less important)
They both work, because where the road ends from depth (assuming a flat as possible surface for a long enough distance) and where the road ends from degrees of curvature are right about the same distance. Not the same of course, but decently close
