I think you're exactly right. Once cars can drive themselves to destinations, it becomes so much easier to get by with one dedicated family car, supplemented with car sharing services.
For example:
Mom takes service to work, possibly carpooling. Dad takes uses family car to drop off kids and goes to work. Car drives itself to mom's work for her to use to pick up kids and commute home. Dad takes service home. Or whatever. The point is kids can always be in the car with the extra diapers, with safety features parents want, etc.
The other part of this that people ignore is that a car sharing service could open up a lot of flexibility. For example, maybe our dedicated family car is just a sedan, but on this particular weekend with the grandparents in town, we can use the car sharing service to get a minivan and have everyone ride together. Or I want to pick up a piece of furniture and request a truck from the service. Or it's my anniversary, and I can request a luxury sedan to drive us to the restaurant for a touch of opulence. I'm sure there are many other examples people can think of.
Like you say, car sharing won't cover everyone's need, especially at first, but eventually, the big players in the space will have enough sophistication to cover many cases, especially for a second car.
