Agreed, in the general sense. I do also think it's important that we not get caught up in holding self-driving cars to an overly high standard, especially in comparison to error prone humans. Speaking only for myself, once self-driving cars are consistently as good as or slightly better than humans, I would find them acceptable for broad use. I don't think the standard needs to be "zero error, ever" although that would be a nice aspirational goal for sure.
