Tesla crash in September showed similarities to fatal Mountain View accident
I have now talked with two people who have autopilot in their model S's and both said the problem with autopilot is that it is "too good". Specifically it works completely correctly like 80 - 90% of the time and as a result, if you use it a lot, you start to expect it to be working and not fail. If it beeps then to tell you to take over, you have to mentally get back into the situational awareness of the road and then decide what to do about it. If that lag time is longer then the time the car has given you to respond, you would likely crash.Makes me wonder how this gets resolved without jumping through the gap to 'perfect' autopilot.
