Thanks Snowdaddy. Yes, I meant 'recognise' via the speed limit info with the maps, rather than via a camera. Although it may be the question arose because TSR is (was?) a feature on some Ateca Xcellence Luxes, using a forward camera behind the rear view mirror. As mentioned here: https://www.seat.com/car-terms/t/traffic-sign-recognition.html
Not sure how much value such a feature would add in practice.
When scrolling through the items on my digi dash yesterday, below speed was 'road signs' it's never been there before so I selected it and had a message saying something like no road signs identified... got back in the car later and it had disappeared off the menu... how strange 😂
