Ah. We might be talking past each other. Looking back, a number of the advantages I mentioned are inherent in having self-driving cars. But the benefits compound when we have shared self-driving cars.

Example:

Traffic is improved with self-driving cars because most traffic jams are caused by humans. However, traffic is improved even more when carpooling is automated with a shared self-driving fleet.

Shared autonomous cars will become popular as these compounded benefits are realized.

I understand the points you're making. But I think you failed to address my question. Let me rephrase.

We have fleets of shared vehicles today, but most people prefer personal transportation.

What is it about autonomous shared cars vs shared cars with a human driver that makes you believe that driverlessness will lead to increased use of shared vehicles vs personal vehicles?
