escalators are actually a bad example of this. What you describe is what is supposed to happen, and they’re supposed to be built with mechanisms to ensure that’s what happens, but there’s been examples of escalators failing in such a way that the weight of too many people on it makes it go faster and faster and people get crushed and deadified.
I watched a youtube video about a famous example a while back, don’t remember the channel that did it though or I’d find and link it.
