Long time Doug fan here...
I've gotten swept into the YouTube car review rabbit hole the last year or two and have managed to watch most of Doug's vids. He has a huge following, both in terms of fans and detractors. And he is a bit of a disruptor as an automotive journalist from... Autotrader. He's paid to write about cars for a used car classified ads website and help generate web traffic with his content, not pander to car companies pushing their latest and greatest offerings.
Doug doesn't wrench on cars and doesn't have any niche automotive hobbies catering to any one crowd (drag racing, track/clubs, offroad, classic car restoration, etc.). Closest he gets is 'cars and coffee'. He was formerly a manager at Porsche North America and he seems to have some degree of knowledge in product development or user experience (or product life-cycles).
Most of his reviews are from the perspective of an average everyday buyer evaluating a product's pros and cons. Cars he reviews aren't limited to new(ish) cars and spans decades of automotive history, also every range of price points. His target audience is probably car-enthusiast middle-aged men who have dreamed about owning fun cars from every era but ultimately drive around something boring and more practical on an everyday basis. Doug reintroduces his audience to cars of the past, cars that are a few years old and now affordable, and halo cars/brands many of us could only dream of owning. Then, evaluates 'features and quirks' on a level playing field. So, door controls on a Ferrari F40 are compared to a Phantom. He's trying to answer the question, "What would it be like to drive and own this car?"
Doug's 4Runner review was absolutely not targeted to the 5th gen T4R crowd and wouldn't offer this group anything new or interesting - although as a 3rd gen owner I was sort of amazed at how feature-deficient the 5th gen was. Doug isn't going to provide any insight into what the next gen 4Runner will look like or delve into specialized tests comparing one vehicle to the next - other than zero-60. That's not his thing. But Doug does accurately point out what the 5th gen is missing or lacking compared to vehicles at a similar price point and production era. He's probably one of the best journalists out there able to evaluate vehicles without fan boy bias and has enough experience reviewing vehicles across the spectrum to provide legitimate insight. Even if he does wear two t-shirts and is weird, awkward and dorky.
