And that's why in real-world you would say "Look in the direction to the
railstation and then the church is on your left."

If you want to describe objects with a handedness you'll need some concept
of sides. If you call it left/right, green/red or "nearer to some related
point at the side"/"farther from ..." doesn't really make a difference.

Perhaps, if always the same proposal is made ("Let's use the order stored
in the db to define a /direction/ of a way and then use "right" and "left"
to /name/ the sides.") this is the most user friendly method?
