I watched a bit of it and it's mostly stating their own conjectures as facts. There's nothing objective about it, it's just pushing their own personal agenda.
Urbanist youtubers inevitably come to mix in some advocacy in their videos. You'd be hard-pressed to find one that isn't critical of car-centric design. That being said, NJB is a well-respected educational youtuber and all their videos are built on a lot of research
Even if you don't agree with the advocacy part of it, I think it's still valuable to watch to get the "urban planning professional" perspective on it
