1. Delivery drones
Most everyone has heard of, and has opinions regarding, Amazon's drone delivery program. Autonomous drones capable of carrying packages would in theory be able to move goods from distribution centers to recipients without requiring a single human to do so.
Ground-based automated delivery isn't out of the question either: Starship has created a small six-wheeled drone that can deliver packages in a two-mile radius. Domino's Pizza has even used them in a pilot program.
