Um, my eyesight ain’t what it used to be, but where are you seeing paving stones on that first picture? I think that is an asphalt. And yes, over here, sometimes only difference between on-kerb parking, cycleway=track and sidewalk=left and might be coloring on the surface and/or a vertical sign.
So yes: in Croatia, that same illegal parking off the street on the first picture might tomorrow become legal car parking, or sidewalk, or cycleway – with only some paint involved, no other road works.
unless your city is building on-kerb parking spaces on raised kerbs
They do. I’m glad someone is having fun at that, as I guess our car drivers probably aren’t
