One other comment John Krafcik, Waymo’s CEO said recently, is that there are weather condition that these systems will never operate in. I believe this was said to lower the bar to help make the massive increase in funds needed look less onerous. While empirically true I believe that if the process I mentioned above were used you could get to a point where these systems can function better than a human in any condition the vehicle itself can handle. The vehicle should be the weak link not the AV systems. DoD aircraft fly in some pretty bad conditions. How has that been possible for over 40 years? The right engineering approach and sensors)
