As this today is the grand prix of Bremgarten on GPRO, fittingly enough, GPLaps has made a great video documenting the history of the venue, and also driving it in AC. Link to video- youtube.com/watch?v=kDkrfQWbGFg
Not sure F1 would be on this track if it still existed today at least not without some serious changes. However, I could see Super Bikes on this track as it was, kind of a smaller Isle of Man.
