I don’t think anyone here is questioning driverless cars from a technical viewpoint. Predicting the advancement of technology is easy since it always does. What is different in this case are legal and government oversight issues. It’s easy to find the defendant in a legal case and determine blame if flattened into a pancake at Bingham Canyon. Not so much if vaporized by a car-drone on a public highway. The subject might make a good futuristic spy novel.
Since this plays right into goverment’s desire to control, I believe that will ride roughshod over the regulatory issues.
