The New York City transit workers are threatening to strike again. It almost happened on Friday morning, but at the last minute they agreed to set a new deadline for Tuesdsay morning.
This demonstrates a significant inefficiency of public transportation. It's no wonder that all modern U.S. cities are car oriented. I'm sure the people who moved away from the New York City to live in places like Phoenix and Denver are glad they can drive to work and not deal with transit strikes.
