The proposal reducedconsumption primarily because: a: tire and wheel friction increase at higher speedsb: engine losses increase at higher speedsc: air friction increases significantly at higher speedsd: car air conditioners become less efficient at higher speedse: None of the above – it was adopted to reduce accidentsJudah Levine, 3070L30 2Clicker questionClicker questionThe 55 miles/hour maximum speed limit was adopted in 1972 as a way saving of gasoline.
