Well, I mean, I'm on your side, I don't think that self-driving cars are going to cause a huge spike in people using car services because having a car you don't have to personally drive is not new technology at all. This may be somewhat cheaper than having a person driving you around or something, but I really think that on balance people will end up having their own personal vehicles.
All I was responding to was that if you grant the parent comment's assertion that people will move to car services, it's very likely to me that rush hour will be the one problem that is very easy to solve, because you would have such a large volume of people all going to the same place. Even the issues with personal space and shared vehicles aren't that big of a problem - self-driving cars don't need to look the way they look now. You could have 4 separate compartments in them, so that it's not possible to touch or interact with the other passengers, for example. (Also, I've participated in casual carpool in both New York and San Francisco, and it works remarkably well - many people, including young women, do travel every day in the car of a complete stranger that they don't know - and it's even more dangerous, because it's controlled by a human driver!)
My guess is, however, that in the future the hardware costs of under-utilized vehicles will be considered to be much lower than the "inconvenience costs" of not having your own vehicle, and rates of car ownership won't be dramatically affected by the advent of the self-driving car.
