Do you guys leave it at default "medium"? I have changed it to "lighter" and it didn't really seem to make a difference. Now that there are light out till past 7pm, I noticed it doesn't turn on till it gets "kinda" dark. I noticed cars around me has their headlights on but my car still doesn't auto turn on. Eventually it does. It's not a pain to turn on myself but just wanted to see if anyone feels the same way?
