I have that light. I don't think it's any more obnoxious than it needs to be. Let's face it, you don't use strobe mode if you're not willing to be at least a little obnoxious. It's not ultra fast like some. If you think it's too bright, you can aim it down a bit.
I don't use strobe mode in the daylight, but I have very little exposure to oncoming traffic hazards either (left crosses) - almost all of my traffic hazard comes from behind. My taillight DOES run in the daytime, on strobe.
