Anthony Levandowski (the Waymo guy) on the robot cabs: "You’re putting the power back into the people’s hands, where a small business owner could have, you know, a fleet of 10 cars or 20 cars that they run themselves as their business. It’s a great model for the future where it’s lots of mom and pops, rather than one mega corp that does that.”
Because that is EXACTLY what will happen and it will absolutely NOT be the case that megacorps will simply do exactly what megacorps do and flood cities with robotaxis running at a loss in order to control the market and then jack up prices. No siree, it'll be all Mom and Pop's Friendly Robotaxi Company.
You forgot to mention that Mom and Pop also benefit from their fleet being linked exclusively to the Robocharge(tm) charging network, which provides reliable charging 24/7 for a simple convenience fee of 25% on top of the local power company's grid rate.
