Need some milk? Driverless cars start delivering groceries

This car is being used in the early stages of the programme out of caution and will be phased out.

America's largest grocery chain stepped into the driverless delivery market Tuesday, bringing milk, eggs and other items to a customer's home in a vehicle with nobody at the wheel.

Although limited to delivering within about 1.5km of one Arizona supermarket owned by Kroger Co, it represents the latest step for industries trying to lower delivery costs of everyday items and those trying to launch self-driving cars on public roads.
