This was really interesting to me-

From KSL's news the other night, a story that kept me thinking about it hours after I heard it. UPS Drivers Discouraged from Making Left Turns

A couple of years ago, United Parcel Service spent 30-million dollars to make its tracking and delivery system more efficient from coast to coast. And yes, left turns are now discouraged.

Steve Goodrich, UPS Community Relations Mgr.: "One, they waste time. Two, it wastes fuel as we idle, waiting for those left turns to happen. And three, left turns are not as safe to make as right turns."

UPS can't eliminate left turns entirely, but the idea is to reduce the number as much as possible.

UPS claims to have reduced their miles traveled by 2 million miles per month using this technology. That's really impressive. But think of the thought process and the application of their computer technology for such a practical use. I just think that is very cool.
