Waited for dark and went out for no reason other than to test them, switched them on and nervously waited for a car to approach, expecting nothing to happen (my usual experience of new tech) and to get angrily flashed at
They actually work brilliantly, very quick to react to oncoming cars and street lights, and they detect the rear lights of a car if you come up behind someone. I had to intervene once as they apparently don’t sense a car side-on i.e. somebody waiting to pull out of a side road
I know I’ve been living under a rock. No real point to this thread except to perhaps ask if others have ever come across a feature well into ownership of a particular car they didn’t know they had?
