But you understand that cars are made to transport people, and hamburgers are much smaller than people, hence it would be a tiny bit wasteful to drive hamburgers in "people cars", right?
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.
It depends on what you consider the goal to be. If the goal is bring a hamburger and person to the same location. It doesn't really matter which is in the car.
A car wouldn't become more productive if you were to strap a person to the roof. If you instead happen to move that person inside the car for the trip, what exactly changes?
