Speed affects pollution

Apparently communication between state agencies concerning air pollution does not exist. In every article concerning the matter, auto emissions are listed as the top cause of pollution.

Nationwide studies confirm that automobiles achieve their greatest gasoline burning efficiency somewhere between 50 and 60 MPH, depending on the make and model. After reaching max efficiency, the percentage of pollutants spewed into the air increases in direct proportion to the increase of speed. Thus, increase of speed by 10 percent results in pollution increase of like proportions.

The state division of air quality has access to these numbers, but evidently did not share them with UTA when it recently opted to increase pollution significantly by raising the speed limit. The anti-pollution help would have been to decrease the speed limit.
