This is rubbish. Lifts (elevators) have fail/safes and built-in redundancy so a cable could snap in use and still be safe to move without danger to any passengers. In the unlikely event that the motor suddenly stopped working, there is a honking great friction brake that would stop the car (albeit with a sudden jolt) after a few feet of descent. Finally, if all else fails, and that would be a lot of failures, there are 'dogs' that move on the rails which guide the cars. They are designed to flip outwards and lock the car in place if the motor friction brake doesn't do its job. The worst that most people would have to endure might be an (usually electronic) failure, causing the car to stop between floors. So, all this 'cables snapping' and 'elevators plummeting' talk is garbage.
