I had no idea that UPS invested so much time and resources in calculating the movements and actions of its drivers. The delivery company is already famous for not making left turns because it's more efficient to make a series of right turns.
But its training facilities teach more than efficient land navigation. There's even a simulator for walking on ice, as well as drills for drivers protecting themselves from dogs and getting into a truck with a minimum number of movements. As this video from Business Insider illustrates, what appears to be a casual if rapid process by drivers is actually precision drill designed to move quickly and safely through the delivery process.
