Because it is physically impossible for low-angle (< 30°) terrain to slide. That said, you can be in low angle but underneath avalanche terrain, and all sorts of other issues, so yes, you need to know what you are doing and stay away from that stuff. I ski some zones where there is just nothing more than about 28°, nothing overhanging, and it's at least as safe as driving on I-70.
AND, yes, some people are idiots. Others are ignorant. That's just part of life.
Hmmmm.. even here in NY we have had one.. Luckily the lodge was closed= the right conditions Snow will Slide
