Er... you watch a youtube channel that uses typical intro slides with someone's facial expressions and arrows (!). I mean, I myself watch EEVblog channel that often include Dave's face on the slide (he's a bit weird and apparently doesn't know better). But arrows! There's literally a prominent red arrow explicitly present in the intro slide of the video you posted! Who in their right mind would watch this kind of slop?

We do fully understand how a bicycle works. A clickbait title above an obvious youtube clickbait video is far from enough to serve as evidence to the contrary
