"I remain to be convinced that the effort to make car driving safer using autonomous-driving technology is viable. The object should be to move the people to where they want to be; to assume that the object is to make safe cars misses the point."
No, mass transit misses the point because, by necessity, it runs to a schedule and to a limited number of fixed points. Life doesn't always run that way, so more often than not you need to travel between two arbitrary points far from any kind of mass transit in conditions that are not conducive to walking (long distances, heavy precipitation, and/or short time limit). Which leaves the car, which has the freedom mass transit lacks. Ask yourself. If mass transit was really all that, why is there still an obsession for a personal form of transportation able to drive anywhere, anytime, and under almost any condition?
