https://en.wikipedia.org/wiki/Double-deck_elevator is like that, but right on top of each other so the range isn't reduced.

Most people are going between the ground floor and whatever floor their destination is on, so a shaft with two cars that go 0-50 and 51-100 wouldn't be very useful.

Actually it's quite common to have cars in the same 'shaft' serving a subset of floors. The original world trade centre towers pioneered this system. Express elevators take you to transfer lobbies and then you transfer to local elevators for intermediate floors. The locals for different sets of levels occupy the same footprint within the building.

Indeed. Same article also covers shared-shaft elevators, exactly as I described.

Ah, sky lobbies are a neat solution to get more efficient use out of the two elevators, I've never encountered one of those!
