In 2019, Walmart started working with a company called Gatik to test autonomous delivery trucks on a two-mile route between a fulfillment center and a store in Bentonville, Arkansas. After those vehicles logged more than 70,000 miles with a human driver there to make sure nothing went wrong, Walmart and Gatik say they're ready for a new challenge. Next year, there won't be any human drivers in the trucks. That milestone will make Gatik one of the first companies in the space to operate a fully autonomous route in this way. As the startup itself is quick to point, it has its simplified approach to thank for the achievement.
