I disagree with the idea that self-driving cars will have the same commodity issue as today's car ride services. How could a significant decrease in operating expenses not increase the profit margin?

Let's put it this way - if you had the choice between paying 1/5th of what you pay now for the cheapest ride available, or half what you pay now for a ride in a nicer, cleaner car that picks you up within seconds, which would you pick? My guess is that with those choices, more people won't pick the cheapest option available.
