Would the comparison not be human drivers? If it's 99% percent reliable I would say that's far safer than humans and makes far more sense already? What am I missing
You think humans are only 99% reliable on a per-mile basis?! That would mean your average person crashes every ~100 miles, or about once every two days.
You can not just go around asserting comparative advantage when your baseline is so far off it is farcical.
