>Driverless ride sharing isn’t coming, in a meaningful way*, in the next ten years, I’m willing to bet my house on that.

You'll have to expand on 'meaningful'. I can see driverless tech being used in specific use-cases between specific locations along controlled or established routes (example, moving cargo between a seaport and the train depot).

I don't see driverless being available as a general purpose consumer vehicle that you can summon to pick up your buddy and drive back to your work.
