true, it definitely depends where you live. If you’re in the US then it’s definitely a case of most don’t work, because most elevators at this point have been made after 1990, but if you live somewhere else then it can definitely be a case of some, or even none

but that said there definitely are functioning crosswalk buttons that work so being pedantic about some, most, etc, is irrelevant because as long as there are any that dont work its relevant to the topic
