It isn't about hand-tuning. I'm still confused by your description of speed limit signs in Finland.
Is the speed limit emitted by LEDs? Why is it ever different between winter and summer? Etc.
If the sign is not white background,no LEDs, and black or red font I as a human would ignore the signage just like the car is probably trained for as that isn't reflective of North America standards.
