That touches some on one of the big potential advantages of having a "cloud" of cheap self-driving cars available. Right now, people need their own car and can mostly only afford one, so they only buy cars that are at least pretty good at everything. And that's like 90% of the market, economies of scale are so strong that car companies don't really make anything but that. Cars that drive on the freeway get a decent advantage from being aerodynamic. And right now, basically nobody wants to buy a car that can't run on the freeway efficiently. If the self-driving car world moves car ownership from individuals to large taxi fleets, then markets open up for all sorts of specialized vehicles. Now we can make something that's super easy to enter and exit but has poor aerodynamics and high-speed handling. They might be awful on the highway, but the self-driving car taxi company will still buy some as long as they have enough non-highway ride requests and interest in the vehicle type.
