I mean, to me at least it is also interesting. Like Japanese writing or Arabic. It's interesting because it is different, there's a different predominant convention. You can also think further about how the writing convention might have had an impact on culture and the society itself.

Also thinking of maps and Japan: where I am from (Germany) public overview maps of parks or street maps usually have north as up. In Japan however it is very common for those maps to have up as the cardinal direction you are looking at the map at. So if you are looking at the map in a western direction, the map will have west up. So for walking the map is straight up, backwards down, left left and right right.

Like that it is very easy to know which way to go. Want to go to some place that is on the left on the map? Turn left!

In the writing example, something that seems inconsequential like right-to-left or left-to-right, does have real implications. Since most people are right-handed, writing right-to-left means they develop writing styles to keep from smearing the ink. In left-to-right writing, it is unnecessary. The consequence is that the minority left-handed people are just taught a mirror of right-handed writing, making left handedness much more of a burden in a left-to-right writing culture.

Yes, I think there are many interesting things to consider about maps (like projection, orientation maps fixed on a panel/wall, orientation for digital maps). All those discussion will also transmit the basic idea (there is no "good/bad" way) while also discussing other problems ("can't represent area well", "people like different options", "different cases require different orientation").
