9. Alpine Slide

Alpine slides were seemingly only conceived in order to make use of steep slopes and save tightfisted theme parks some dollars. The concept is very simple: build a breakneck, winding concrete trackway with shallow edges down a huge freakin’ hill and let the general public fly down it on a ludicrously temperamental cart with a mostly useless handbrake. Aside from obvious risks such as grazing one’s body practically to the bone upon bailing, actual deaths aren’t unheard of, with one unfortunate individual at a certain East Coast theme park hitting his head fatally against a rock when his cart derailed.
