You're misunderstanding the data and the concern. Currently, Tesla Autopilot frequently disengages as part of its expected operation, handing control back to the driver. Thus, the human driver remains an attentive and competent partner to the autopilot system. That data is based on today's effective partnership between human and computer.
The concern is that as level 2 autopilot gets better and disengagements go down, the human's attentiveness will degrade, making the remaining disengagement scenarios more dangerous.

If the autopilot keeps itself in situations where it does better than humans most (not all) of the time, the system will outperform. My view isn't one of technological optimism. Its derived from the low bar set by humans.
- nostrademons 9y agoThe problem is that in L2, the bar for the system as a whole is set by the low bar for humans, specifically their reactions in an emergency. If the computer safely drives itself 99% of the time but in that 1% when the human needs to take control, the human fucks up, the occupants of the vehicle are still dead. And what people are saying here is that L2 automation increases the risk that the human will fuck up in that 1%, by decreasing their situational awareness in the remainder of time. That's why Google concluded that L5 was the only way to go. You only get the benefit of computers being smarter than humans if the computer is in charge 100% of the time, which requires that its performance in the 1% of situations where there is an emergency must be better than the human's performance. That is the low bar to meet, but you still have to meet it.

And what people are saying here is that L2 automation increases the risk that the human will fuck up in that 1%, by decreasing their situational awareness in the remainder of time. Humans regularly mess up in supposedly-safe scenarios. Consider a machine that kills everyone in those 1% edge cases (which are in reality less frequent than 1%) and drives perfectly 99% of the time. I hypothesise it would still outperform humans. Of course, you won't have 100% death in the edge cases. Either way, making the majority of travel safe in exchange for making edge cases more deadly to untrained drivers has a simple solution: a higher bar for licensing human drivers.
- notheguyouthink 9y agoYou make an important point. This is something I see a lot of people gloss over in these discussions. It's a question that both sides of the discussion claim answers to, and both sound reasonable. The only real answer is data. As you've said, killing 100% of the time in the 1% scenarios may very well be better than humans driving all the time. Better, as defined by less human life lost / injuries. Though, one minor addition to that - is human perception. Even if numerically I've got a better chance to survive, not be injured, etc - in a 99% perfect auto-car, I'm not sure I'd buy it. Knowing that if I hear that buzzer I'm very likely to die is.. a bit unsettling. Personally I'm just hoping for more advanced cruise control with radar identifying 2+ cars ahead of me knowing about upcoming stops/etc. It's a nice middle ground for me, until we get the Lvl5 thing.
- nolemurs 9y ago> I'd hypothesise that a machine that kills everyone in those 1% edge cases (which are actually less frequent than 1%) but drives perfectly 99% of the time would still outperform humans. Well, no. Some quick googling suggests that the fatality rate right now is roughly 1 per 100 million miles. So, for certain fatality in the case of human control to be an improvement, it would have to happen only about once in the lifespan of about every 500 million cars. In other words, the car would, for all practical purposes, have to be self driving.
- ethbro 9y agoWhy not just mix in consensus-control, artificially generated disengagements? Even if the system has high confidence in its ability to handle a situation, if sufficient time has passed, request the driver resume control. Then fusion the driver's inputs w/ the system's for either additional training data or backseat safety driving (e.g. system monitoring human driver).
- abalone 9y agoI like your creative thinking, but that wouldn't work. An immediate problem is it would only train the driver to pay attention when they hear a disengagement chime. L2 depends on the driver to monitor the autopilot continuously. More productively, Tesla currently senses hands on the wheel. Perhaps they could extend that with an interior camera that visually analyzes the driver's face to ensure their eyes are on the the road.
- chc 9y agoThey actually have a driver-facing camera in the Model 3, which is presumably coming to their other cars in a future refresh.
- MBCook 9y agoRecent Honda CRVs can have a attention monitoring system in them. I'm not sure how it works but it does seem to detect when the driver isn't looking around.
