Not to trivialize it, but one thing it will do is hit the brakes a lot faster than any of us could. That's number one. Number two, to reinforce what Mr. Kirk has been saying, is that on average the accident rate will go down dramatically, because that's not the typical situation that causes an accident. Over 90% of accidents are caused by human factors, and there's a whole range of them, from inattention to drunken driving to purposely running red lights—you name it.
All of those things are going to go away with CAVs. Yes, there will be some cases, but they will be such a small percentage of the collision risk situations that they'll be a rounding error compared to what we're experiencing right now.
As I say, and I don't mean to trivialize it, for one thing, they'll be able to hit the brakes a lot quicker and they may be programmed to make wiser decisions than you or I would make.
