My point is that given all vehicles in Autodriving mode... there WILL BE NO (or very few) inevitable crashes. Your car will see/sense/be told there is a stopped or potentially hazardous bus ahead and an oncoming truck as well. It will know it FAR SOONER, than you would, as the sole sensory/monitoring system especially given that perhaps you are thinking about your job, the football game, or listening to NPR/Rush on satellite radio. Your Autopilot will know everything in all cars within X radius and will know there is an accident because a deer crossed the road, 2 miles up which is resulting in all the cars between you and it to slow and merge. All cars between you and it will also be in communication, and slowing slightly to allow the fastest and safest merging possible for all involved, thereby preventing your last second decision on whether you take out the Kindergartener's field trip bus or take one for the team and head-on the Semi.
(Not only that, but with IR sensors... the initial car wreck would likely have been avoided or decreased in likelihood, because the car would have seen the deer off the shoulder while you were dazzled by a monster truck's headlights which seemed to be on bright.)
