- Need for speed? Driving above the speed limit costs you — and doesn’t actually save much time
A study found that driving above the speed limit costs drivers money in fuel and increases emissions but saves minimal time. Adhering to posted speed limits could save $22 million daily, 6.7 million gallons of fuel, and 57,000 metric tonnes of CO2 in the U.S., with only a 54-second daily time increase per trip. Researchers analyzed 120 million trips and found 43% of trips included speeding, with significant state-level variations in speeding prevalence.
- Need for speed? Driving above the speed limit costs you — and doesn't actually save much time
A study found that driving above speed limits wastes fuel and emissions without saving significant time, with 43% of trips including speeding. Adhering to speed limits could save $22 million daily, 6.7 million gallons of fuel, and reduce 57,000 metric tonnes of CO2. Driving at limits adds only 54 seconds to a 28.6-mile daily commute.
- Need for speed? UMN researchers say arriving above the speed limit costs you — and doesn’t actually save much time
University of Minnesota researchers found that driving above speed limits in the U.S. wastes fuel and emissions without significantly saving time. Adhering to speed limits could save $22 million daily, 6.7 million gallons of fuel, and 57,000 metric tonnes of CO2, based on 2021 data from 120 million trips.
- POLL OF THE DAY: Should speed limits be cut to 20mph in all built-up areas across England?
A poll is asking whether speed limits should be reduced to 20mph in all built-up areas across England. The proposal focuses on changing traffic regulations in urban settings.
