The only time I've ridden with a flashing front I had to stop to get a stick to put between my teeth so I wouldn't swallow my tongue while I tried to figure out how to turn it off. I hated it. Can't even ponder HAVING a flashing headlight, and have no idea how others can stand it. As far as meeting up with those blinking folks instead of being one, it bugs me a bit but we're past each other fast enough that I don't much care.
I do have issues with the high-aimed retina searers and the helment-mounted light wearers who feel compelled to stare at you, as they are downright infringing on me (and it is, of course, all about me). But for the rest of the menagerie, c'est la vie, free world, I may not fathom how you can want to do what you're doing, but carry on.
