Google's sister-company Waymo has announced a trial in which its self-driving cars will ferry shoppers to and from a nearby Walmart store to pick up their groceries.
For now, the pilot is being restricted to 400-plus members of its early rider programme in Phoenix, Arizona.
However, it indicates how the tech giant thinks the autonomous vehicles could be deployed if and when they exit the experimental stage.
One expert said cost would be key.
The only word on pricing so far is a promise to offer participants discounts when they order goods via Walmart's Online Grocery Pickup service as part of the deal.
"If this is rolled out properly you would expect there to be a reasonably high threshold in terms of the price and spend commitment to justify the service," commented Julie Palmer, a retail expert at the consultancy Begbies Traynor.
