 Where is traffic the worst in the U.S., and how much time are we losing sitting in it? If you live in New York, Chicago, L.A., Boston, or Miami, we feel for you. Those are the top five cities for traffic congestion, according to Inrix, a company that studies transportation analytics. Its new survey says American drivers lose an average of 42 work hours in a typical year because they're sitting in traffic. The survey also shows congestion is up since before the pandemic, and mass transit ridership is down. ABC's Sherry Preston.
