It is because the automatic speech to text program YouTube uses can be pretty bad.
Unless a transcript is uploaded with the video, the auto subtitles are often useless.

I watch some car videos on youtube (Matt’s off road rescues, Jay Leno’s garage, etc.)

I always get a kick when the various wonderful car noises (tires, engine, etc.) get subtitled as “music” or “applause” - it fits! (That turbo is music to my ears.)
