It's ugly (and unhealthy) out there

Riverside/San Bernardino was No. 1 and Los Angeles was No. 3 in the Forbes.com list of the most unhealthy commutes in America. We are talking accidents, bad air, stress etc. Here's the, uh, methodology to the Forbes assessment:

To figure out which region is faring worst, we looked at three issues facing the country's 25 largest metropolitan areas. First, we examined year-round particle pollution levels based on rankings by the American Lung Assn., which used air-monitoring data that states submitted to the U.S. Environmental Protection Agency from 2003-05. To estimate the time people spend in rush-hour traffic, we used the Texas Transportation Institute's 2005 Urban Mobility Report, which calculated annual delays per traveler during peak hours in urban areas nationwide. Finally, to get a sense of how dangerous the roads are, we compiled the number of per-capita fatal car accidents each region had in 2005 using the U.S. Department of Transportation's Fatality Analysis Reporting System.
