That's partly an effect of being on HN.
In non tech circles - the vast majority of the world - people are pretty famous for measuring risks by perception and not statistics.
The idea of a robotic truck taking away jobs while also being a risk to life? America would take up mass transit before it buys into that system.
Man I can see the headlines and political/ emotional arguments now. Godless SV tech priests rob Americans of the last few jobs they have. 1% and automation, no job left behind.!
It's useful to remember that People refused seat belts until the argument was irrefutable. Hell doctors didn't wash hands regularly until it was drilled into their heads that they were infecting patients.
And when it come to automated personal care - I bet that People will utterly, vociferously, oppose the loss of their agency in controlling their means of movement.
People have romanticized the man and the horse, the man and the bike, the car - but it's because it's a matter of controlling that power.
Selling that to the American public and the world at large is a multi generational effort.
