Yeah, this is a misunderstanding of speed limits by the app developer. In the UK, as far as I remember, these national speed limit roads have just never had a speed limit put on them. Things like accidents, petitions, zoning etc. is how everywhere else has gradually added speed limits.
So although you could say “well, national speed limit on a single carriageway is 60mph” by default, that has almost nothing to do with how fast people are able drive on them. To work that out, you’d probably have to do some Waze-type stuff.
I’ve very sympathetic to the developers. It’s a stupidly hard problem to know what speed is likely, at what time of day, on these roads. Far far easier to just have the data of what people are actually doing on these roads. That’s what Google do.
Though if you can detect country road, you could safely assume half the speed advertised.
It’s also cultural. Country roads in my country are 90 km/h and unless it’s dangerous, that’s what you would do on them. Which means speed is lower than posted in tight spots and curves, but not normal roads.
I love these roads and the British countryside, but it is definitely an eyes wide open environment. Certainly can be a shortcut, but often SatNavs without traffic info, use them when they really shouldn’t. You used to often see signs telling people to ignore their SatNavs and not take this road, but it’s less of a thing now as everyone just uses Google Maps. Basically, I want that traffic info as public access for all SatNavs. Not locked away.

That’s pretty much the UK really. Only you are very rarely able to get close to the 60mph limit at all, let alone safely.
The are more dangerous by statistics. Some random links:
