- Need for speed? Driving above the speed limit costs you — and doesn't actually save much time
A study by the University of Minnesota found that driving above speed limits wastes fuel and emissions but saves minimal time. Adhering to speed limits could save $22 million daily, 6.7 million gallons of fuel, and 57,000 metric tonnes of CO2, with drivers adding only 54 seconds to their daily commutes. Analysis of 120 million trips revealed significant regional variations in speeding prevalence and excess.
