That's not actually a blocking problem, as you have the same issues with human drivers today. At the end of the day, just like literally everything else in life, self-driving tech is a statistical process with corresponding costs. The bar for success here isn't perfection. Rather, it's whether or not self-driving vehicles are cheaper than human-driven vehicles. Part of the cost of a self-driving vehicle hinges on how often the vehicles end up in failure states necessitating remote human intervention and/or insurance payouts. It's fine if they sometimes fail, they just have to do so infrequently enough to be cheaper. And if Waymo is to be trusted, they already appear to be safer.
