The best scenario is to have the road fully illuminated, but also the shoulders/ditches on each side - that's usually where you'll see the animals, just before they make a bound onto the road in a dash for the other side.Geez that's a pretty picture.
You say that bending lights help with "wildlife on the move" but wouldn't that only be true of say deer crossing the road from left to right as you were into a left hand curve? It seems that with the lights bending left, if a deer came in from the right side, the DBL would actually not be in position to spot the approaching herbivore as well as fixed lights would.
The DBLs do an excellent job of that as you go around a curve - bending to keep that broad sweep and illuminating the inside of the curve which is normally blacked out. I've lived in the foothills of the mountains all my life, and seen some of the carnage that results to both animals and vehicles (and occupants!) when they meet - the difference in useful illumination is quite pronounced, and most welcome.
