How much time is the average metropolitan citizen sitting in traffic every year?

The average time a metropolitan citizen spends sitting in traffic every year can vary greatly depending on the city. For example, according to the INRIX 2018 Global Traffic Scorecard, the average American spent 97 hours a year in traffic, while in Moscow and Istanbul, the average was 210 hours. In Bogota, drivers lost 272 hours, or over 11 days, to traffic in 2018. However, these numbers can vary year by year and city by city. To get a more accurate answer, you would need to look up traffic data for the specific metropolitan area you're interested in.
