We may be one step closer to having our mail delivered by robots.
The U.S. Postal Service on Tuesday started a two-week test transporting mail across three Southwestern states using self-driving trucks, a step forward in the effort to commercialize autonomous vehicle technology for hauling freight.
The autonomous vehicles are being used on the long-haul route between Phoenix and Dallas. A camera system allows the self-driving trucks to see more than 32-hundred feet ahead.
The postal service is looking for ways to cut costs after several years of losing money due to declines in letter volume.
