Riding to work on the dark on Monday, was confronted by a gent with a big old CREE pointed into my face and set to flashing. Yes, I could spot him a mile off but the combination of aim, brightness and flashing was such that I had zero hope of estimating his speed, movement or direction of travel, and I was virtually atop him before my eyes could resolve that he was indeed in the same road coming toward me. His efforts to make himself safer had seriously compromised his safety.
I'm all for big, bad lights, but the manner of its use was well beyond the sensible.
