Pittsburgh is being named one of the nation’s most stressful cities for drivers. That is according to a recent study released by Lemon Law Experts. Rankings were based on surveys taken by residents in 40 major U.S. cities, looking at factors including traffic density and driver temperament. Pittsburgh landed at ninth most stressful on the list, with Atlanta, Nashville and Philadelphia ranked as the top three. Neither New York City nor Los Angeles, both known for heavy traffic, placed in the top 10.
