Subways are used as a weapon against #publictransit.

Subways send people underground to make room for private autos on the street above. In addition, subways are extremely expensive and use up public transit funds which are hard to get through political systems dominated by friends of oil, auto, and sprawl. Subways encourage long commutes.

Fare-Free New Zealand: ""Our idea, however, has been discarded by the city in place of a costly subway construction project and we're still trying to find out why," said Ghidini."

If you reduce or eliminate cars from your city, you will have plenty of room for buses and light rail. New subway construction will not be needed.
