Those who enjoy carving skiing might have already noticed this little problem: Carving without skiing poles can be a lot of fun, but as soon as you line up for the ski-lift, getting ahead can become really hazardous. Things are worse on an uneven surface; once your skis start following gravity, there's not much you can do against it (unless you find someone to hold on to). I am still waiting for an invention to prevent carving skis from moving when you don't want them to. Quite logically, such an invention would need a security mechanism to keep it from deploying while skiing.
