Compare that to most household products with a thousand warning labels for things that are common sense and/or completely harmless. Like do idiots not go skiing or something?
Do you really expect a human to usefully monitor the whole thing continuously? If you look at a modern lift, there is quite an array of sensors on each tower.
> no way to stop in an emergency
There's an emergency stop button at both ends. They get used on a regular basis due to emergencies. By far the most common emergency is someone falling in the loading or unloading area. (I think a lot of high capacity lifts actually have multiple emergency stop buttons at each end so that any of several operators can stop the lifts.)
(I don’t know about the legalities of that as a contract, but it’s how it’s almost always done at ski resorts.)
