It doesn't feel realistic or immersive to wait only 30 secs for an elevator. Realistically we should be waiting a few minutes or more each elevator. I think it really adds to the immersion and allows time for all the other immersive high fidelity game play activities possible while waiting for elevators. Also, sometimes the elevator opens straight away, this is very unrealistic, I'd much prefer it always took a few minutes to arrive. Also, when travelling in the elevator it is often really quick. I think it's much more realistic and immersive to be stuck in a high fidelity floating coffin for long periods of time.
