> Self-driving cars will save tens of thousands of lives a year and hundreds of thousands of expensive fender-benders, whether due to sleepiness, inattention, or drunk driving. This claim is the part of self-driving cars that has become boring. People keep making it, but they never specify when, nor do we get any information about whether full-self-driving is really that big a safety leap over the automatic braking and lane assist that we have already had for a decade or more. Meanwhile there remains no appreciable effect on the slope of the graph for annual deaths per vehicle miles traveled.
