I started watching his channel back when he did the turn signal video a few years ago. I was skeptical at first because I had seen his videos pop up in my recommended a few times and wasn't interested in them, but after giving it a chance I love his content and watch most of his videos all the way through.
The only videos I haven't watched in their entirety are the ones on subjects I'm already pretty familiar with. It's hard to sit through 40 minutes of information you already know, but they're excellent for learning about new topics.
