Pizza delivery - in the not too distant future
In the not too distant future...
"Hey Google, order me a pizza – the usual, but a large this time, and have it delivered."
Pizza is loaded into an autonomous vehicle containing a pizza oven that cooks it on the way to me.
Autonomous vehicle texts me when 2 minutes away.
I meet it at the curb. It authenticates me using voice or facial recognition and gives me the pizza.
