A self-driving Nuro vehicle parks outside a Fry's supermarket, which is owned by Kroger, as part of a pilot program for grocery deliveries Thursday, Aug. 16, 2018, in Scottsdale, Ariz. Kroger Co. has chosen the Phoenix suburb as a test market for delivering groceries using driverless cars. The Toyota Prius will be used for the deliveries, manned by a human to monitor its performance. During phase two in the fall, deliveries will be made by a completely autonomous vehicle, called an R1, with no human aboard. (AP Photo/Ross D. Franklin)
