I'm really looking forward to this tech -- I recently was at fault in a highway chain-reaction accident where I was trying to merge right, and looked over my right shoulder at exactly the time when the car in front of me stood on his brakes. WHAM! With collision avoidance, which many carmakers are shipping in high-end cars, I would have safely stopped. (The car behind me, fortunately, had allowed more distance and was looking ahead -- and didn't hit me.)<p>This video is quite similar; it's not showing anything unique to Tesla, but it does show the promise of systems that are not subject to human attention FAIL.
