The United States has 5% of the world’s population and 30% of the world’s automobiles, but it contributes 45% of the world’s automotive CO2 emissions.http://www.edf.org/sites/default/files/5301_Globalwarmingontheroad_0.pdf
In 2004, U.S. cars and light trucks emitted 314 million metric tons of carbon-equivalent (MMTc). That equals the amount of carbon in a coal train 50,000 miles long—enough to stretch 17 times between New York and San Francisco. In fact, the amount of CO2 emitted from oil used for transportation in the United States is similar to the amount from coal used to generate electricity.

Disproportionate media coverage also can stimulate transit fear. Because transit accidents and assaults are infrequent, they tend to receive significant media coverage (Martin 2011). A fatal train or bus crash, or transit terrorism attack, often produces intense national and international media coverage, whereas fatal automobile crashes are so common they are usually reported only locally.
In addition, transit organizations can unintentionally increase fear with safety and security messages that emphasize dangers, including dramatic but unlikely threats such as terrorism, without counterbalancing messages about transit’s overall safety, such as those illustrated in Figure 9.
