The implication is that driving over the speed limit is likely, on average, to be less fuel efficient than obeying it. Due to the laws of human nature, very few people drive significantly below the speed limit, and very few people prioritise their fuel economy over everything else so this translates to a reasonable guideline.
- tremon 10y agoThe implication is that driving over the speed limit is likely, on average, to be less fuel efficient than obeying it. Not necessarily, because of gear changes. Not all cars can use 5th gear in a 50km/h zone, so they'll drive in 4th gear. It seems likely that doing 60km/h in 5th gear is more efficient than 50km/h in 4th gear.
