Ask Slashdot: If Public Transport Was Free, Would You Leave Your Car At Home?

dkatana writes: The Estonian capital launched a program of free public transport to encourage people to leave their cars at home. But they never did. When Tallinn launched the program ridership numbers did increase, but not by the 20% the city had projected. Instead, they grew by a modest 3%, and by people already using public transport. What happened is that more pedestrians and bike users started to use public transit instead of walking and cycling. But car users continue to drive to work. Do you think the same would hold true in the U.S. if a similar program was started?
