NASCAR and F1 have been dropping in viewership and attendance. Not from specifically a lack of crashes, but relatively uninteresting competition. The overtakes are rare and the battles rarely happen. The same is happening in F1. There is so much dirty air that passing is impossible.
I don't think that anybody wants to see people get hurt, we want to see good competitive racing. For motor racing, that means overtakes, rivalry, and the occasional touch. For ski racing that might be not making the turns... unfortunately at the Hannenkham and other downhills, if the brakes aren't used that means usually going into the fence or worse. We just don't have the capabilities for run-offs and safety zones on every turn like the motor racing world can afford. It's unfortunate that we don't have the area to make the area safer for skiers.
But on the other hand, it is quite amazing that skiers will still throw themselves down these courses.
