I’m here to tell you many people simply cannot accurately process 1 light and two wheels as being another vehicle particularly at night, when the motorcycle is coming towards them. Their brains are looking for a box with two lights. Saw a rider get creamed this way one dark morning a few years ago. He was doing everything right (bright clothes, right of way, etc.) and the SUV turned right into his path. My guess is other oncoming headlights confused or drowned out his headlight giving the appearance of the rider being further away.
Then there are the people on meds, diabetics with morning blurred vision, etc.
That accident reminded me why I gave up riding in my 20s -after a very similar incident happened to me. I only lost a chunk out of my calf which eventually healed.
