I also find that the speed limiter not infrequently picks up "20 MPH Zone" markings from side roads in towns. At least once that caused a very unexpected and rapid speed reduction from 30 MPH to 20 MPH which must have been a brown trouser job for the driver behind me who wouldn't have seen any reason for it!
Therefore seldom or never do I use it.

I never use the automated speed limiter, I just set it to a flat speed. The speed sign feature I've tried on AAOS and Sensus - it's just as bad on each, both seeing local 70mph dual carriageway (part of the A1 no less) as a 60mph road for example. Thankfully easy to permanently break the link from the signs to the limiter on these cars.
The system is bad on every car I've driven - picks up side roads as main roads, has historical limits on it etc.
I'm not a fan of using cruise in busy traffic or through road works but the limiter is very useful for that. 50 average? Set it to 55 and forget, car overreads a little anyway and it stops you finding you're doing 58mph because the driver in front isn't concentrating.
