Get Yer Bread and Milk From Kroger's Cute New Delivery Robot

Ask most of the people developing autonomous vehicles how robo-cars will change the world, and most will say safety--more than a million people die on the road every year, and self-driving cars could prevent some of those deaths. Some might say smarter cars can battle congestion. Ask Dave Ferguson, though, and he'll pitch the idea that this technology could make moving about so efficient and affordable that transportation becomes effectively free. But first, before the zeroes and ones can do any of that, they may bring you your groceries. If you shop at Kroger, that is, and are cool with a Lilliputian pseudo-car pulling into your driveway all by itself.
