I might be wrong, but I think this is where a lot of the misconception stems from. In Norway it also shows the (usually) correct visualization, but it never use it. People have done a lot of testing and it seemingly always use map data. But this might be different in different regions. From my understanding this is where a lot of the "phantom breaking" on highways comes from. The map data shows a temporary slower speed sign due to previous construction.

In Australia, a lot of buses have a 40kmph sign on the back to show you should pass the bus at 40 when stopped - but it's laid out and coloured the same as road signs.

Every time I'm behind a bus in my Tesla, it reads the sign on the bus, displays it on the scren as the current limit, and sometimes (arbitrarily it seems) if I have autopilot on it reduces the maximum allowed speed to 40.

I can't speak for the logic run elsewhere, but AU Teslas for sure use it.
