Honking, squeaking brakes and bumper-to-bumper traffic are common problems in many of America’s congested cities. Frustrated drivers can get agitated quickly and their aggressive driving habits like speeding, rapid acceleration and braking can lower gas mileage by as much as 40 percent, costing them as much as $477 per year in additional fuel consumption. GasBuddy reveals the major metropolitan areas in the United States with the most aggressive drivers, causing them to pay more for gasoline by making more frequent trips to the pump.

GasBuddy compiled data from its Drives feature in the GasBuddy app, examining the top 30 metropolitan areas by population as defined by the United States Census Bureau from Nov. 2018 - Feb. 2019, noting the frequency of an aggressive event while driving, whether it be speeding, hard braking or accelerating.
