Elevator designers have tried all sorts of solutions to deal with our endless frustration with any delay. Algorithms allow the lifts to anticipate demand and minimize wait time. Mitsubishi created one that rises as fast as a plane—over forty feet a second. But we’re still tapping our feet and rolling our eyes. Not fast enough. They’ve realized we can wait about fifteen seconds on average. At forty seconds, we start clenching our fists. When surveyed, people who had to wait two minutes report it as ten minutes.
