Domino's Pizza CEO Patrick Doyle, who is set to retire in June from his role, told TheStreet that in about three to five years at the earliest he expects driverless cars and voice orders to shift the way the world orders pizza:

"We have been investing in natural voice for ordering for a few years. We rolled that out in our own apps before Amazon launched Alexa and Alphabet launched Google Home...[and] we are making investments...to understand how consumers will want to interact with autonomous vehicles and pizza delivery" — Patrick Doyle, Domino's Pizza CEO
