Hmm...What you said about the Rapid X3 has me scratching my head. A couple months ago I came up on a guy using a very interesting rear lamp. I was sitting at a stop light when I noticed the cyclist over at the light to my right. I noticed at the time that his rear light was very visible from the front as he was at a good 45° angle to my right. His light changed first and I watch him go through the light. ( night time, urban setting with street lamps ) When my light changed I had a chance to view his light directly from behind. Not bad, visible but not overwhelmingly bright. I'm sure in a darker setting there would of been more contrast. When I caught him at the next light I looked at his light but didn't know at the time what brand it was. I just knew it had two separate panels of leds, angled slightly on each side. This light was VERY bright from the sides with almost a 360° visible output. Later I saw pictures of the Cateye X3 and figured that was the light I saw. Okay it's bright but it's a micro-led paneled light. As such the light is VERY dispersed, even more so because the panels are angled. Anyway, just my take on the X3.

Agree. Both cameras and video can't really represent all of what the human eye can actually see.
