But does the average driver know that? It is their perception that's important here. The Utah driver expected the car would not fly her into the mountain, so to speak. Naming, marketing context of self driving alongside this feature, and driver instruction are all likely part of the puzzle.

If you think the name has nothing to do with it, would you also say that if it had the name "Deluxe Cruise Control" people would treat it the same? I'm not so sure about that. Engineers maybe.
