The problem with Tesla’s ‘autopilot’ is that it’s anything but. Asking drivers to keep their eyes on the road and hands on the wheel while not steering guarantees that their attention will wander, because their brain isn’t getting enough stimulus to keep focused on the task. I don’t know why it’s not clear to most people by now. The current Tesla ‘autopilot’ is simply more dangerous than manual driving because it har…

I am curious how do aircraft pilots got around this? Autopilot on aircraft work same as a Tesla drive a straight line where I aimed you have way less interaction than on the car. Yet pilots are able to take over autopilot and their responsibility during it's use is mostly looking out the window and occasionally switching frequency

One key difference is how much time operators have to figure out what's going on before action is necessary. If an aircraft autopilot fails, time before crash is likely measured in minutes, so the pilot taking 10 seconds to snap back into pilot mode still gives a pretty good likelihood of a favorable outcome. In a car, 10 seconds of no or bad driving on the part of the autopilot is pretty likely to cause a collision.

Even so, it's been implicated in crashes, notably Air France 447.

I think it is possible that the Tempe police chief and mayor anticipated the incident could be a problem for them, especially given the secret agreement that later came out, and chose to try to spin the story on their own account. It is not hard to imagine that, in that frame of mind, they might be receptive to someone from Uber saying "clearly this was unavoidable", but I have no way of knowing whether any such conv…

It's of tremendous importance from the perspective of public perception of who's at fault.

If the average observer watching the published video arrives at a conclusion of "well I would have hit that person too, she appeared out of nowhere in front of the car", it obviously matters.

Background: My wife drives a Tesla Model S with AP. Inattentive drivers more than overconfident drivers. You look down and stare at your phone for 10 seconds in a normal car and you are punished pretty quickly and learn not to do it. You look down and start at your phone for 10 seconds in a Tesla with AP and "nothing bad happens" ... almost all of the time. And that's the problem with this version of AP. Yes, Tesla s…

This is in HCI 101; we learned this by air traffic controllers crashing planes.

It's not important at all. There's a bug in Uber's software. That's what we should be talking about.

My guess is that they are unhappy because Tesla has decided they hold no responsibility. They blame 1) the driver and 2) Caltrans (for not maintaining the median). The NTSB doesn't like to speculate. They like to have solid facts, and they want the manufacturer to take blame if need be, so they can fix things.

Also they're interested in minimising risk in the future and providing recommendations to achieve that. It may well be the case that in a strict legal sense Tesla has no responsibility here, but from the NTSB's point of view that's irrelevant—the question is whether there's anything Tesla could do to minimise the risk of future incidents like this.

If Tesla relies so heavily on lane markers, someone may very well perform "a hit" on one or more Tesla owners by painting some adversarial lane lines. They could even tuned to the spectral response of the Tesla sensor pack.

> It seems the local government or highway agency also neglected their duty to maintain the highway safety barrier, a shockingly regular occurrence where I live as well. I’ve wondered how often someone is injured because they failed to repair a barrier for several months. While the crash attenuators should exist and the various responsible authorities should maintain them appropriately, I find it frustrating that thi…

I understand what you’re saying completely. The point of highway safety equipment is usually as a last resort to minimize injury as much as possible, this is after markings, signage, drivers and vehicles have failed to prevent a crash. Obviously the crash should’ve been avoided, but poorly maintained or designed infrastructure should not be left out of the conversation.

I think it's best to split these in to two 'investigations' to talk about. Yep the barrier probably contributed to the death but are we really interested in talking about? We're here to talk about the self-driving bit! We wouldn't be talking about it if it was a 2002 Toyota Camry that hit it..

It does seem that there is a problem with the vehicle's lidar or the associated software, so does it not strike you as strange that the story being pushed claimed that the victim "came out of the shadows", which is a misleading irrelevance if lidar is the primary sensing technology? Especially as the unrealistically dark video does not even seem to fit that story.

Yes. That's why I am posting in this thread.

Uber has said essentially nothing about their crash, it's the cops who rushed out and got nearly everything wrong. Uber clearly had a serious technical failure, but there's been no PR spin from them.

It seems like the dash cam video released is very misleading there's been a couple people who've driven through the same area at night and it is well lit. [0] From the Uber cam it seems like the light is still on because there's a bright glow about where streetlights are in the other videos. It's kind of shocking just how bad the dash cam of the incident actually is unless the lights were recently (because there's still the glow) off for some reason before dawn (poorly implemented scheduling maybe?).

The difference between the Uber dash cam [1] and the one posted to youtube is stark [2]. It's certainly darker where she comes from but no where near impossible. Source the ArsTechnica article [3]
