Couldn't we have self-driving food trucks, each specializing in a specific food? People could have events and schedules a couple of food trucks to drive by while cooking food on the way. Fast food takes on a new meaning (fast vehicles cook+deliver food on demand). No more need for fast food restaurants because they just can transformed into a fleet of trucks.
