Both of my cars (BMW and Nissan) have the ability to auto-switch to low beams when oncoming headlights are detected. It works great. But you have to press a button on the end of the turn signal wand to enable it. And it disables when you turn the car off. My wife and kids have no idea how to use this feature. I tried to explain it a few times, but they weren't interested.
