According to the 2014 Fuel Economy Guide, the average car runs at maximum efficiency at 50-55 mph, emitting about 5 tons of greenhouse gas per year at that speed. At 80 mph, emissions rise to 9 tons almost twice as much.
Despite these facts, our Legislature just raised the speed limit to 80 in some areas, which would nearly double toxic emissions.
Does anyone else find this odd at a time when we are trying to cut pollution? Wouldn't it make more sense to lower, not raise the speed limit?
