I'm not sure self driving vehicles will magically make food delivery profitable. Sure, self driving cars can bring the food to the front of my door or house, but how will the food get into my place? Maybe that's okay for a sandwich for one person, but a soon as we're talkang about a complete meal for two or more people, it becomes a completely different story.

Are people really willing to pay a premium delivery fee, only to have to carry the heavy or hot packages themselves into the house, elevator, appartement? In the rain, cold or snow? In the dark?

Self driving food delivery has a 'last mile' problem. Sure you can transport the food to my sidewalk that way, but how do you get it to or over my doorstep without ruining the whole convenience experience, in a sustainable and profitable way?
