Ford and Domino's Pizza have teamed up to see whether customers like having their food delivered by driverless cars. Some pizzas in Ann Arbor, Michigan, are arriving in a specially designed Ford Fusion fitted with radars and a camera used for autonomous testing.

A Ford engineer will be at the wheel, but customers will have to head outside and type a four-digit code into a keypad on the car to access a heated compartment with their food.

Ford and Domino’s said the six-week test will help them learn how customers react to driverless cars — including whether they will venture outside if it is raining or snowing.
