Motorsports injury and survival rates have been impacted by:
- Hans device
- improved cage technology
- unibody/tub/energy absorption design
- tire/suspension/materials technology
- computer aids
- spill zones & traps
- course design
- sight lines
- better EMS education/training/expertise
- evacuation transport chain
- improved trauma protocols
- data acquisition/communication
In skiing, many of these improvements have been implemented.
Fencing technology, spill zones, hill prep are as optimized as possible given the constraints of many traditional courses. One option would be to design new courses that are inherently safer, but this would destroy much of the culture of the sport.
World cup medical staff, training, simuation, protocols, and evac systems are on par with F1/Indy/ALMS.
Ultimately you just can't get around the fact that plastic boots and long skis are virtually purpose built to transfer energy up the chain - in ways that aren't always pleasant. Speed and impact loads often match or exceed motorsports collisions, but until you can strap a skier inside a 'car', I don't think there's much to be done.
Re. the bracing, faceguard, padding issue, it's the old argument of rugby vs. football. It's a trade off between perceived protection and speed/freedom of movement.
On that topic - I doubt there's any amount of bracing, head protection, or padding that would have helped Albrecht. He simply - and sadly - exceeded the design threshold of the human body. I hope he does ok, but I suspect that's going to be a career ending - and maybe life changing - injury
Lastly, if you watched the SuperG at Kitz today, there were A LOT of oh sh*t moments - many of the guys were on the edge of disaster at least once during the run. Speeds are up, equipment is more demanding and more precise, the guys are fitter and stronger, and the field is deeper. As a consequence everyone is exploring - and often exceeding - their limits.
