Yet new analysis from Global Traffic Scorecard, based on metrics from INRIX, has placed Chicago as the city with the worst traffic in America, tipping NYC off the top spot from last year.
The research has found drivers in the Windy City lose a staggering 112 hours per year sitting in traffic on average, a hike of 10 per cent from the previous year and coming in at more than double the average (49 hours) of time lost in congestion across the entire country.
However, Chicago isn't the worst of the bunch, with the city ranking third globally for bad traffic, behind Mexico City and Istanbul, the worst offender.
New York City, Philadelphia, Los Angeles, Boston, Miami, Atlanta, Houston, Washington and Seattle were also considered amongst the worst US cities for traffic.
Interestingly, Baltimore and Philadelphia shot to the top of this year's list for having the largest congestion increase in the top 25 cities, with delays hiking by 31 per cent in each, costing drivers more than $85 billion in lost productivity.
