For someone who craves total darkness for my star-gazing activities, I am pathologically averse to the dark when driving or riding. Give me a 12volt sun on the front of my car or bike and I am a very happy bunny; with a dip of course...
So what is it with almost every car I encounter in the dark and dead of night when they NEVER, EVER go to main beam. Unless they are coming toward me of course...
When a vehicle come t'other way I dip just before their lights become visible (ish) and go back to main beam somewhere between the front of their vehicle and the back of it, passing me.
But I can drive for miles wondering where the road goes, behind some eejit who must think, as in the old days, that using main beam actually costs you money. Of course, on the bike it is less of a problem but even so....
