In mere existence terms... It exists, my cars almost detect correctly all speed limits it see around, almost because sometimes it detect wrong one or for a wrong road tract (like a temporary limit due to some road works, kept after that just because there is a missing end sign), but in mandatory (present and on by default) means that we will get wrong actions, as per phantom breaks (I got three in three last days, for instance, in one case exaggerated and too hard, the other two for not valid reasons though not hard).

That's aside the mere fact we should been able to ignore speed limits under specific circumstances that's are typically emergencies so we do not have time to dig in the vehicle tablet menu to deactivate some ADAS...
