Would this translate into cheaper operating costs and stamp costs?

While I suspect it may have something to do with what the above poster mentioned, there was an interesting article/report about UPS changing their routes so drivers pretty much only had to make right hand turns - lefts were avoided as much as possible, and the amount of gas and money saved was ridiculous. It was a few years old but I'll see if I can find the link...
Edit: that wasn't very hard

UPS trucks drove 2.5 billion miles last year, but the company says its package flow technology combined with right-turn routes saved 28,541,472 million miles, and three million gallons of fuel. The company puts almost 92,000 trucks on the road every day. But without its efficiency and right-turn routes, it would have to send out an additional 1,100 trucks.
