UPDATE – The HSARC is now broadcasting their races live on YouTube! They broadcast their first races this past weekend. It’s worth watching the races to get a sense of what their track looks like and how the cars run on it. https://www.youtube.com/watch?v=Xh-zr43UVh4&t=45s.
They will be broadcasting the DTM Proxy races. They will be installing more cameras for more views in the very near future.
