I have really enjoyed hearing about this story which has been circulating around various media sources for some time now.
Apparently UPS have for a long time planned their driving routes to make mostly right turns. It is calculated that as many as 90% of the total turns made by their drivers are to the right. Sounds unbelievable doesn't it? Really it's not!
This has significantly reduced the amount of gas wasted while sitting idling at intersections waiting to make left turns, reduced distances travelled, and it has of course cut down on air pollution, and carbon emissions. In turn it is saving UPS a whole lot of gas money and time. What a brilliant, and deceptively simple idea!
