It's interesting to see the consonants follow a pattern like this. In swedish it's fack, with a harder k-sound, and many words are like this comparing germanic words.
Ah, the speed limit signs themselves also. This section is limited to 50 km/h, and this one is 60 km/h. Ok so far? The next one is simply marked "not 60" good luck.
Is that iust americans being used to arbitrary speed limits meaning signs EVERYWHERE?
Where I live, its 50 in towns, 100 outside of towns. Meaning there will only be signs when it's not the default for some reason, like a school zone, road work etc.
We have this in Australia too. In built-up areas (think a town or city) the default limit is 50km/h, and outside of those it's 100km/h. You'll often have a speed limit of 80km/h as you head out of a small town on a country highway, and then an "End 80" sign to indicate you can drive the default 100km/h.
