Why don’t we stop building escalators until we find the answer to why they don’t work in San Francisco but do work in other cities.
Is it a design flaw? Is it a management issue? Is there a built in obsolescence feature such as some people suggest? A giant sucking magnetic force that renders all escalator’s unable to function properly? How can we continue to build systems that never work? Let’s just stop building them until we figure out why.
How we people going to deal with broken escalators at the Central Subway stations when they malfunction? Will they put up with a steep long climb?
Find a city where escalators work, find what who designed them and why they work there, and try to use a proven design and contractor in San Francisco and on the BART systems. Solve the mystery before continuing to build more broken elevators.
