> George Hotz makes some good points about Waymo. At best it's a slower Uber (drives more timidly and slower) with the potential to be cheaper. So let's customers trade time for money. But uber pool already does that and accounts for about 10% of rides - in other words it's not a trade off the market demands.

I don't think that's the same thing. I don't like uber pool because it's very unpredictable, not just that it's slow. If it were predictably slow, I might use it more.
