I'd say the Adaptive Lights (in fact the whole Vis Pack) is worth every penny!
In fact the video even paints a slightly simplistic version of it in action. I've been on a dual carriageway in lane #2 following a car while overtaking cars in lane #1 with the adaptive lights switching on/off nearside verge illumination in the gaps between the vehicles I'm overtaking. At the same time it's coping with traffic in front of me and coming towards me on the opposite side of the carriageway - really amazing
