This is the St. Peter am Kammersberg hillclimb in the Austrian Alps, 1988. You get to see some of the coolest racing cars in the world, and you get to see them crash.
Yes, back in the day people used to run Porsche
935s RSRs, monsters that charged down the Mulsanne Straight at 235 178 miles an hour, up tiny one-lane mountain roads. Unsurprisingly, they crashed with some regularity.
The announcer makes it sound like everyone made it out of this video okay, despite tearing their lustworthy classic race cars into tiny shreds.
