At least in Finland, probably in Sweden too speed limits change often (every 6 months) due to winter. In my experience the GPS databases are extremely often not in sync, and you can't predict which speed limits change and when. In addition, there are electronic speed limits that change depending on the weather in real-time. OCR seems like a better option for these conditions.
