When you look straight AT a driver's face, they will see ONLY that light. That is 100% NOT what you want.
That is what happened to me, riding my bike in Sandpoint ID on a dark street at night. I had NO clue where his bike was or was going. He was coming towards me. Same thing in other situations, ALL I could see was the stupid light. He was 15 feet away before I knew what he was riding.
