How does a ski area mandate personal responsibility? I may be wrong, but, I don't think the primary mission of the Patrol is to ID and eliminate dangerous skiers. Personally, I would not want to be the on the force responsible for enforcement. Like it or not, the skiing culture is akin to "buyer beware"...you pay your money and take your chances.
My belief is that management of ski areas does not want to be in the business of pulling passes based on subjective observations. Please tell me how I objectively know that someone is skiing in control? Anybody ever see speed limit signs and is a GPS in your goggles a requirement to know how fast you are going? OK, I've seen "slow skiiing area" banners, but, rarely is there someone to enforce it. We rant about boarders, but, people training on GS skis scares the heck out of me. Is random testing for alcohol done in a lift line at your local hill. Heck, my mountain will sell you plenty of cans of beer.
Not trying to condone unsafe behavior, but, the next time one of us passes a novice skier at high speed and with, what we consider a safe margin, how do you know that skier does not consider us a hazard? The "code" is a guideline at best, and, there are always two sides to a story. Shared negligence is a way of life in our legal system.
