OK, I need to hear some other Miata driver's thoughts on this matter.
My wife has asked me on a number of occasions, to put my headlights on/up while I drive on the highway so I am more visible to other traffic. She feels the dark green car is harder to see as well.
I tell her that my driving lights are on, and that I don't like the looks of the barn doors being up when it's a beautiful sunny day (I do use my headlights in the daytime when it rains, or is foggy).
So, the question... What lengths do you take while driving the Miata to be safe, and where do you draw the line?
