i disagree again, making cars isn't the competitive advantage it's being able to run and service large fleets of cars, taxi / bus companies with all the physical plants would have the competitive advantage out of the gate.

I disagree, if you make the cars you can create them from the ground up to be self driving taxis. Think of all the improvements you could make to make better use of the cabin.

If you are retrofitting existing cars you are wasting a ton of money and getting a half baked solution to a dedicated provider.
