OpenStreetMap
Don’t Overdo It
Use as few nodes as possible, but as many as necessary. This makes it much easier for later mappers to improve or update things.
Keep Consistent Distance Between Nodes
Makes rendered maps look much nicer :)
Follow Road’s Centerline

I broadly agree, but would like to point out that for those willing to use JOSM, UtilsPlugin2 provides the very useful Circle Arc tool. I use it a lot.
I like iD. Without it I most likely would have never started editing OpenStreetMap. But I advise people to learn JOSM. The investment will soon pay back.

Great tip! It seems there’s a JOSM plugin for everything. Obviously it’s the more powerful option for editing, but after trying to get used to it several times I can’t seem to get over that initial wall of unfamiliarity. I suppose one of these days I should make myself switch over and reap some of the benefits you describe…

If you have an official map, maybe the official centerline is the best.

I’d add a sub-point to “Keep Consistent Distance Between Nodes”: node spacing should be proportional to curvature:
That way the angular spacing is more consistent and we use nodes where they are the most useful.

I hate when the map in my region has a childish look.

I completely disagree with the don’t overdo it.
Go as detailed as possible in general let’s say a meter or so max level (dependant on the curvature) the example you gave as ‘too detailed’ I think is fine. Your ‘perfect one’ was IMHO terrible and needs at least double the amount of points.
Your reasoning for not adding more points is that someone may need to update in the future. My question is why? The road in question will likely stay that way for decades and a really well mapped curve will not need any changes made to it for all that time. What are they going to update? If the road changes significantly then the whole thing will need to be remapped anyway.
I say with time permitting map it as detailed as you can. The result will be there for a long time.
(I have other issues with that curve too it is to far aligned to one side it should be in the middle of the road and the connecting road should be more curved to reflect what the road….but I digress)

no, we are mapping reality
if reality and official map diverges, then we should ignore official map
if they match then we can just follow reality
