Not sure if youre being sarcastic, but this sign in Germany means that all previous (velocity) restrictions are lifted and the overall speed limit is valid (on "Landstraße"/country road => 100 km/h, "Autobahn"/Highway => theoretically unlimited km/h... well you still have to drive "according to the circumstances" which is important in case an accident occurs, so visibility, rain/snow, only two lanes etc.).
There is no direct context to parking.
My initial thought when reading your comment was a response about differentiation of both hemispheres, but the way you wrote it was actually quite clever, so kudos for that! :D
Funny that you mentioned ONI, played and enjoyed it for > 50 hrs but I always got to the point where the base was falling apart b/c of one of the many missing ressources for my dupes :o So actually quite stressful at times, at least for me :D
Tbf thats pretty similar
