But while the idea of sinking your teeth into a tasty slice can be appealing, the bummer is the pesky delivery guy, who loiters in the doorway judging your slovenly outfit and your measly tip. They're fully enclosed, four-wheeled carbohydrate-dispensing machines, complete with heated and cooled, lockable compartments that require the purchaser to enter a passcode to retrieve their delivered food. Its space-age, Kubrickian exterior styling is sure to appeal to middle-age sci-fi geeks as well as neighborhood paintball enthusiasts. Domino's Pizza--which happens to share its hometown of Ann Arbor, Michigan, with Car and Driver--has a long history of delivery innovation, including in recent years electric vehicles and Chevrolet Spark–based custom delivery wagons. When it came time to go robotic, Domino's called in Australian technology startup Marathon Targets to help in the creation of its autonomous delivery vehicles.
