...my X1 has something called "Limit Assist".
When enabled, and in conjunction with the speed limiter function, it gives a dashboard warning when the speed limit changes (according to the SatNav Data), and a single flick of the up/down switch will adjust the speed limiter immediately to that new speed (no need to explicitly and manually set the speed).
Entirely undocumented (at least in my manual) is the fact that it is also linked to the front windscreen camera, normally utilised only for "imminent" collision warnings, and it recognises speed limit signs, most noticeably temporary ones, which are out of step with the SatNav data.
It occurred to me that, though the SatNav data was showing original road speed data through roadworks, prominent temporary 30mph signs were being recognised, and the limit assist functioning accordingly.
I've since confirmed it empirically.
