Re: Yep, that's my understanding of events
You also have to wonder a bit if they're fudging a bit on "what it's supposed to do". By definition the car should be following all the rules of the road including following other vehicles at an appropriate distance, watching for turn signals, signalling, checking lanes before you switch, etc.
Now while I'd like to follow all those rules all the time, the simple fact of the matter is that given where I live and drive, I can't. Everybody else on the road here seems to define "safe following distance" as aligning your front bumper at about the midpoint of the rear quarter panel of the car next to you. Give them any more distance than that and they will cut you off with an unsignalled lane change. Speaking of which, turn signals were obviously meant to be optional equipment not mandatory. If you can't tell by the positioning of the car that he's about to change lanes, too bad sucker. One of my favorite moves is the Maryland Double. In this maneuver you turn from the second lane on a multilane highway through the right lane before executing your actual turn onto the exit ramp. All within about 50 yards of the hard separation of the exit lane. The other day I had the pleasure of watching someone execute the Quadruple Maryland. (And people wonder why our car insurance rates are so high here.)
So if they've had to adapt their programming to take care of real world problems yeah, I can see a near miss on a lane change. And in a certain sense, it still is "doing what it's supposed to do."
