I've seen 30 recognized as 80mph. Clearly the system didn't even have a plausibility check: in the UK 80mph isn't a legal limit!

It also gets confused when there are overpasses or tunnels crossing the road, and the nav-based speed limit flips from 70mph to 15mph to 70mph.

ah i have seen 80 before, that could explain it it was never clear to me if it was reading the signs or just basing it off of map data
