Yeah, according to Tom Tom (the GPS Maker):

Not only is our city the most congested, but also the bumper-to-bumper traffic is so bad this year that it’s rated as the highest in L.A. since the study started six years ago. This may explain all that road rage. TomTom looked into 53 heavily populated metropolitan areas and found that we lose 11.5 days a year to sitting on the roads, tearing our hair out.

Only thing not clear from this story are we Number 1 in worst traffic in America, or in the world?
