This planet money follows a UPS truck where sensors & big data lead to small changes that make large bottom line impacts: 1 minute per driver per day over the course of a year adds up to $14.5M. One keystroke per driver costs $100K/year. 1 minute of idle per driver per day is worth $500K in additional fuel costs at the end of the year. Shaving all this time via efficiencies worked for the workers too. In the last decade, their wages & benefits have doubled.
