Just Like Derek Zoolander, UPS Drivers Can’t Turn Left

Each day, UPS drivers deliver an average of 120 packages. The number of potential route combinations for a driver is “far greater than the number of nanoseconds the earth has existed” (2). To ensure UPS drivers use “the most optimized delivery routes in regard to distance, fuel and time”, UPS began developing On-Road Integrated Optimization and Navigation (ORION) software in 2003, which included eliminating left turns (2).
