The USPS is Building a Self-Driving Mail Truck

One final idea floated by the USPS Office of the Inspector General in the report. Mail carriers drive the same exact routes almost every day. If the service kits out its vans with the right sorts of sensors, those vans could build and constantly update the incredibly detailed 3-D maps that help self-driving cars navigate—for a price, of course. Yeah, other startups and companies have been built expressly to collect and mine mapping data—but don’t count out the letter carriers. If rain and hail can’t stop them, why should the future?
