When the Tesla autopilot disengages because it doesn't detect your hands on the wheel, it takes a large number of seconds with increasingly obnoxious dashboard and audio warnings. It's hard to miss if you're paying any attention at all. Is “contemporary cruise control” constant-speed, or traffic aware? Having driven tens of thousands of miles with each, I feel that the first increases the chance of an accident and the second decreases it (unless you let it lull you into ignoring the road). Tesla's cruise control has some blind spots (going around a curve into stopped traffic), but they're complementary to my own blind spots (the car in front suddenly decelerates; zoning out in stop-and-go traffic); my subjective impression is that the two of us together are much safer.
