Coming up to the top of a hill is worst as no matter how well adjusted their dipped beam is a car approaching from the brow of a hill will at some be point be shining headlamps directly into your eyes.
I had an unusual incident in broad daylight yesterday whilst walking the dog along a gentle upward sloping footpath. A new Mini topped the brow of slope ahead with extremely bright headlamps. Don't know whether they were focused DRL's or the owner hadn't discovered the auto headlamp switch yet but every light was illuminated including front fogs. It was the headlamps though that left me temporarily blinded. My eyes were way above the height of a Morgan or even SUV driver!
