But then a single car can carry multiple hamburgers to multiple people! Maybe that is still a better situation than multiple people driving multiple cars to each get a single hamburger :-)
So we need a car that drives around and makes hamburgers on-demand, drives to your home while it's being prepared, and delivers it hot and fresh to your door with a smaller bot.
To be clear, we do not need this, and I am being sarcastic. However, if a VC wants to fund me to do this, I'll try my best in the hours between my use of the startup's office sim-rig and the office wood workshop.
