With liberty and freedom comes both risk and responsibility on the part of the individual. But it is impossible to regulate all behavior. Not only does it take away individual liberty and freedom, it also takes away personal responsibility and accountability, as well as common sense.
I take great risk with my own life and the lives of others when I ski every weekend flying down a run at 70mph and playing on jibs and jumps. Even when I go that fast, there are still some that go flying by me. Everyone on the mountain knows there is danger of hitting someone or something or having someone else hit them. Even with this risk I have yet to run into another skier or boarder on the mountain as I know, due to personal responsibility, when I can go fast and the conditions (snow conditions, visibility, and the number of people on the slope) that are conducive to specific speeds. I know if I hit someone in front of me it is my fault, no matter how fast I am going as downhill skiers have the right of way. Most of the accidents I see are from beginners going very slow and running into another beginner going slow as both are still learning how to turn.
Because accidents do occur and always will at a ski resort, the mountain takes great care on their own to make it as safe as possible. The last thing I want to see is the government telling all ski resorts how they should regulate skiing and boarding. The worst thing that can happen is for the government making them post speed limits, limits on the size, steepness, and number of jibs (rails, boxes, walls, ex), as well as the size and number of jumps. It is those that actually partake in the events on each particular mountain that have the best knowledge of how things should be on the mountain. It is those that actually pay to ski and board that know their own limits and risks involved in trying knew things, and it is these skier and boarders that are responsible for their own actions.
This applies to driving as well. As a driver I know what distracts me and what doesn't. I also know there are drivers that are easily distracted by many things, including the radio in their car, and I am risking my life getting on the road with them. The last thing I want to do is to give up my freedom to listen to my radio (I know that is not part of this particular proposal, but it is a distraction and can save lives if it is banded) in my car or use my hands free device because others do not know how to use either without being distracted.
