For anyone watching that video, and are interested in watching more classic racing in incredibly high fidelity, I recommend this collection of clips from the 1966 movie "Grand Prix". It's a proper old-school Hollywood movie.
They entered actual Formula 1 cars into a grand prix, strapped it with cameras, and recorded the whole thing. Other times they added new bodywork to a Formula 2 car and had the actors driving around on track - again with cameras strapped to the car. Being recorded in 70mm it's some of the best footage of on-board Formula 1 racing until well into the 2010s, and the advent of small 4k on-board cameras in modern races.
