For certain you cannot prevent all accidents, and I am not trying to say that we can/should. I think having a sole operator in a prototype vehicle drastically increases the odds of these accidents, and that companies like Waymo should run them with two operators and some drowsiness detection systems (which are common on luxury cars). That’s a relatively simple fix. It’s important that testing with multi ton moving vehicles be handled with far more cars than most production databases are, speaking to your metaphor. The consequences of mistakes is much much higher with cars than it is with most databases.
