Moscow is in a class of its own. Drivers in the IBM study reported the average delay being 2.5 hours, with more than 40 percent of respondents claiming to have been stuck in traffic for more than three hours. By contrast, 25 percent of the commuters surveyed in Buenos Aires (a city of similar size) reported never having been stuck.
