However, like railroad safety is expensive heavily regulated, self driving car companies have the same issue.
Decentralized driving decentralizes risk.
so when I have my _own_ robot to do it, it'll be easy and cheap.
Sure, in theory. In practice, nobody is going to give up control on the basis that the machine is "slightly better than average". Those who consider the safety data when making their decision will demand a system that's just as good as the best human drivers in most aspects.
And speaking of Waymo, let's not forget that they only operate in a handful of places. Their safety data doesn't generalize outside of those areas.
Yeah, I'm curious in seeing how they function in environments that get snow.
