Thanks for the clarification. That's weird as mine seems to cope with them fine. I am in country Victoria and it has no trouble interpreting temporary road work signs like you have linked in rural areas.Nope. I'm talking about bog standard metal non-electronic 80km/h Road Work signs on poles at the side of the road. There were 3 to 4 of these on each side of the motorway in both directions.
They pretty much looked like this: 80km ROAD WORK 900x1745mm CLASS 1 - ROAD SIGNS | Hi-Vis Mining
It also has no problem with signs like this. where the visualiser momentarily displays it as 40 before the screen image changes to the circle with diagonal line to indication end of speed restriction. OTOH coming in to a town where it might say "60 ahead" the car will slow at this sign instead of the subsequent "60" sign. But I like this behaviour.
Out of interest, here is a gantry variable sign ex the dashcam.
