> Whenever I speak to laypeople about self driving cars their mind immediately shoots to the 1 million+ ways that things can go terribly wrong, or even slightly wrong.

When I raved about self driving cars to my wife, she said to me: look, Google Maps is messing up on a continuous basis (GPS errors, software errors, bad routes, mapping inconsistencies, underestimated ETA). If they can't make a decent GPS app, how could they make a self driving car?

I had no way to counter that. It's true, GPS is an old tech purposefully dumbed down for non-military applications. But how can we convince people of progress when it is so lacking?
