Less miles don't always translate to lower costs. We've already discussed the increased labor, UPS's greatest cost. If Orion shaves 3 miles off a route each day, that's about $1.25 savings in gas. If it increases our paid day a conservative 15 minutes, that's about $12.50 (OT). UPS's primary goal should be saving labor costs. Gas is dirt cheap compared to labor.
Crazy thing is is that many drivers report an increase in both.
The other thing that had come to mind is that not all miles are created equal. Orion believes they are. We all know that highway miles use less gas and is much less wear and tear on the vehicle. If I'm making an intelligent decision, I'll take a highway route that is 12 miles vs. the high traffic stop and go direct route that is 9 miles. The highway trip is quicker and much less use of brakes, transmission, suspension, ect. Orion will choose the 9 mile route ultimately costing the company more.
