This is a good point also. Oddly enough it's the LED taillights that get me on this topic. Very easy to notice if you are glancing around.

Yes! This drives me crazy. But I mention it to others, (and how to experience it), and their eyes don't perceive it. What % of people are sensitive to this? Any medical documentation? Is NHTSA aware?

The LED tail lights remind me of the target strobe meant to trigger the accompanying toys. Of course if you're old like me, you probably only watched an episode to see what Lightwave3d was capable of, but ..
