Have they ever worked for you in the locations that you tested?
Its been a while since I have driven the car to test 50mph signs (and national). When the speed sign recognition first came out, I raised the issue of some 50 and 70mph signs were not being picked up [UK] 2020.36.x. The response came back that speed sign recognition only worked for 'local roads' - the roads that I were testing were dual carriage ways, and slip roads, so accepted that explanation. Over a few releases, I noticed a couple of national signs being recognised, but speed change not actioned - I seem to be an outlier with that. But the 50 and nationals on my test route still not recognised.
I'm just trying to work out if the local roads restriction has subsequently been lifted. I've not noticed it in any release notes.
I've never seen NSL recognised (as it's variable depending on conditions it may be beyond the current system to do so anyway). Definitely seen 60 and 50 recognised but not actioned (I've never seen AP action a speed limit change, which I've never been able to explain compared to others experience).
There are definitely roads though where it 'turns off' and completely fails to recognise even 30s. Doesn't seem consistent which roads.. there's probably some algorithm somewhere that decides if a road is 'local' but I'm damned if I can work out what it is..
