I came across this article and thought it was pretty interesting… especially now with the price of gas going up.
[B]Right turn process saves money [I]and [/I]the environment[/B]
On any given day, UPS delivers 15.8 million packages and documents around the world. Their delivery fleet consists of 93,637 package cars, vans, tractors and motorcycles. Those signature brown UPS trucks are everywhere! You can’t help but notice them on the road. But here’s something you may not have noticed: UPS trucks don’t turn left. Well, ok, sometimes they have to turn left. But 90 percent of the time, they only make right turns. It’s part of their operating procedures to avoid making left turns.

In 2004, after evaluating their CO2 emissions, UPS announced that its drivers would avoid making left turns. They calculated that the amount of time spent idling waiting to make a left turn would save millions of dollars in fuel costs every year. For example, in 2006 UPS trucks drove 2.5 billion miles, and with their unique package flow technology combined with their right-turn routes, they estimate saving 28,541,472 million miles, and three million gallons of fuel. Talk about improving the bottom line!
