Guess you should've better explained what the point of switching shafts is? looks like it takes quite some time to do that, so... why?,(reply>), well outside of building transfer it allows for the same cab to carry you up more of a building. many structures dont have a shaft from bottom level to top so you need to go up say 40 then change to a different cab that services 40 to 80 for example. this would go up 40.. over to next shaft.. then continue up 40 more. this gives building engineers more options on structural core designs that dont depend on extremely long shafts to cater to.,(reply>), Srsly? You cant see the potential?<br><br>You could walk into a elevator in Building A and press the button to go to building B and the elevator could actual do that.<br><br>There could be a bridge between buildings (or even underground tunnels) that connects them with horizontal shafts of this elevator.<br><br>Imagine being on top floor of skyscrapper 1 and wanting to get to the top floor of skyscrapper 2. With this elevator it would be possible in a few minutes. Without the need to change cabs or even do one foot step.
