At first I wasn't sure about the format, but with giving it a more relaxed viewing

I don't hink they've captured it well, especially from still image stock.
I always want more time to study each of the images as they contain such detail, initially frustrated that they pass quickly, but then appreciate that the sequences being from still image then realised it was either shot like that or coincidentally they realised that it could make effective moving record.
Quite clever really.
I first rode a Jota over that way, picking it up for a friend as I was insured, located south of Dorking on A24

Notice it was on Technicolour too, their motion picture laboratory was originally over on the bath road north side of Heathrow that did all the facsimile rolls for cinema projection. My dad worked there after he left technical college as first job.
Good find Dave.
