Every car is more affordable when you don't have to pay a human being to operate it. The difference in labor costs dwarfs the difference in vehicle costs.
It's been a while since I looked it up but I understand the human is about 50% of taxi operating costs. That's not trivial of course but it's also not dwarfing vehicle costs.
