Also, respectfully, most people who live in CA have very little idea about the mechanics of how to drive a car - they never had to learn because of the lack of the aforementioned precipitation - so it's actually a lot easier for Waymo to get to the same level as you because you are all bad drivers (mechanically, not in terms of politeness or rule-following). In CA I frequently got asked whether I ever did amateur racing or go-karting as a child, and when I learned that this was about how I handled a car (at first I thought it was just an odd inquiry about a specific hobby), I politely informed them that I did not, but I learned to drive in an icy version of hell.
I am hopeful, but it's going to be a long slog, and at the pace it took Waymos to become average-to-below-average drivers in SF, I assume it will be 10+ years before self-driving cars come to my area in a serious way.
