This.

My car is my property. I own it. It does everything I want it to. It is an extension of me.

That question is like asking, "Why own a computer? Why not hire a mathematician to do all your computation for you?"

The problems a self-driving problem solves are 100x deeper than a human, and the second order effects to greater society are enormous. When everyone and everything is self-driving, the roads aren't roads any more - they're TCP/IP and logistics super highways. Anything can go anywhere for any reason at any time. This is a huge societal unlock.

Even thinking about how frictionful ordering an Uber is is exhausting when thinking about the idyllic future of simply jumping into my own car - my own space - and having it do exactly what I want.

This future is magical and I want it now.
