Washington, DC’s Metro system recently enacted a random police search policy for its riders, citing increased security concerns for the decision. But in reality, the new policy does nothing to protect people from terrorist attacks and pushes people away from public transit and into cars.
Which is the bigger threat: a terrorist attack on a train or the greenhouse gases that spew from cars stuck in rush hour traffic?

The high cost of gas has pushed retail gas purchases down 2 to 3 percent. What are people doing instead? Taking public transportation!
The first quarter report from the American Public Transportation Association (APTA) found that use of public transportation is skyrocketing in tandem with gas prices. Last year 10.3 billion trips were taken on U.S. public transportation — the highest in 50 years. Ridership on streetcars, trolleys, commuter rails, subways, and buses are all up. Even Amtrak ridership is soaring.
This shift presents an historic opportunity.
It was hard to get us Americans out of our cars when gas was cheap, but now we’re trying public transportation in record numbers. And once people try it, odds are they’ll prefer it, which is great news for the environment.
Good public transportation is more pleasant than a private car (you can’t read while you’re driving), and far cheaper. A calculator on the APTA Web site shows how much you can save by leaving your car parked at home.
