I do not think so, the LED lights are just really bright. The human eye is most sensitive to green light. And according to the following graph similarly much to reddish and bluish tones (maybe even more sensitive to the yellow stuff rather than blue) https://www.researchgate.net/figure/The-eye-sensitivity-function-7_fig17_343319896

Supposedly car manufacturers even brag about their stupid bright lights, so I do think they put effort into making their lights more and more bright, even if they try containing the beams to the street. I couldn’t find Mercedes’ original ad to this picture though: https://knowyourmeme.com/photos/2556223

I’m not entirely sure, but I think some players used to do shenanigans where they walked around looking straight up while walking crouched and then activating and deactivating the scope again and again, which made the character either look wonky or doing suggestive hip movements. Often when one player started it, a couple of others joined and they did like a polonaise. It was beautiful and both teams forgot their fighting for a moment and just went as a sniper train around the map. I might be confusing this with the protocol for dealing with spy crabs though.

In case this is an honest question: it is the sniper from Team Fortress 2

Awesome meme!

I would say both. You need to learn by trying things out, making your own mistakes and finding a style. Then you get input from the outside world on why some peculiar structure make sense or just giving helpful tips. Then you try out more, apply those tips and see what works for you. But you can read as much helpful input as you want, it won’t be any good without you trying to apply it and practice.
