This self-driving grocery store has no employees

The idea of a fully automated grocery store with no human employees might sound strange (or very appealing, depending on just how much you hate interacting with people), and now, Shanghai residents can visit one for themselves. The Swedish company Wheelys is testing a mobile grocery store with no staff -- and it can drive itself. In order to shop at Moby, you first have to download an app to your phone. That's what gets you through the door, which is otherwise kept locked. You then walk through the store -- which is very small, fitting a maximum of four people at once -- and place your purchases into a smart basket.
