No Sign of Stagnation

From Building the Skyline by Jason Barr:
"The new One World Trade Center will have the fastest cars in the Western Hemisphere, operating at a top speed of 2,000 feet a minute, though a relative snail compared with the Burj Khalifa, which delivers its tenants to any of its 164 floors at a rate of 3,543 feet per minute.
…Maximum [elevator] speed has increased at an average annual rate of 1.7% since 1913."
