I doubt that is a thought on anyone's mind... I find people orient themselves by the direction their house / street faces, to a lesser extent the position of the sun, and north at the top is a completely arbitrary thing imposed on us.

As evidence, see GPS navigation, which shows "forward" at the top.

Agree. It's also often that Upwards has a literal meaning, where the Upper place is literally geographically higher than the Lower place. Think of Lower Saxony, which is in the northern part of Germany, for example.
