Oh boy, “Mobility Justice” is also a thing. Starting in California:
“We should be expanding no turn on red to every neighborhood.”
Although the practice has never been found to reduce emissions or gas consumption, the measure was adopted as a way to cut down on idling cars at red lights during the 1970s oil crisis.
Hang on a minute… then why does UPS do this? 
“A left-hand turn is also less fuel efficient,” said Jack Levis, UPS Senior Director of Process Management, “because your car’s idling longer, which is also not good for your vehicle.”
