I am a big fan of real Mexican food too and definitely not the Tex-Mex stuff. Thankfully, I have found a couple of really good places around here. A few tacos and a good habanero sauce are my favorites. Preferably with a good cerveza or two.

Still the only thing I miss about Mexico today is the street tacos.

Well done, sir!
I did genuinely think that that one would cause problems. Moral of the story? Never try to guess how hard or easy your clue might be.

Now I want to see how they show why their little monster did what it did, how it will react in other situations and how to 'cure' it from its delusions.
The AI fans always forget that even the dumbest human driver has a few million years of evolution behind him. How can they think to play better in the same league with x hours of training and 'testing'?

They haven't released the video footage, but the reports say it was her fault - she walked out in front of it so close than nothing could have prevented the collision, human or robotic driver: Tempe police chief: Uber 'likely' not at fault in fatal self-driving car crash - Business Insider[^]
And you can be sure that there is more telemetry and recorded info in this accident than in any previous death-by-driving case, with the possible exception of Ayrton Senna...

That may be. There are certainly hopeless situations. Still, no telemetry in the world is going to tell us why the AI did or did not do something. Would you like to have to make any guarantees for the behavior of your contraption? They don't have to become Terminators to be dangerous.

Do you know what the "emergency brake" used to be for? Do you why it is now the "parking brake" instead?
Do you know what anti-lock brakes are for? Do you know why they are safer, for most people, than versus the alternative, for most people, in the past?
What about when cars will not stop? This happens apparently more than I thought because I found the following looking for the other example that I know exists.
Driver was unable to stop or slow down his car[^]
So perhaps you don't drive at all, but everyone else already relies on the behavior of their "contraption".

Yeah well I would dispute that, we've all been in that situation driving along where nobody is in front of you but they are near enough that you keep your eyes open - people walking close to the edge of the road, kids playing football in front of their house, dog walkers with the dog jumping about ...
If this woman "walked out in front of it so close than nothing could have prevented the collision" seems likely she was already close to the edge of the road, most humans would (1) gently nudge the car away from that lane/road edge before reaching (I'm sure in Az the lanes are wide enough), and (2) pay extra attention to watch for change of direction.
There's more to driving then what does happen, but being ready for what else can happen - yes some things are completely unexpected but where you can anticipate these possibilities you can and should be prepared. You see a drunk on the road do you pass within inches or wait till a nice big gap appears...

You are describing a good human driver, what about the many deaths daily caused by detracted, dangerous drivers.
By the time this technology makes it to the mainstream, all the bugs will be sorted out and the roads will be a far safer place, current dangerous and careless driving offenses will no longer exist.

Really? How will they do that? How do you unit test the AI? How do you prove that your AI can deal with any circumstances a very complex world throws at it?
Look at how miserably we fail at testing normal code made up of simple, limited functions. From where do you take the optimism that this will miraculously work for something as complex as an AI?

How do we do it with human drivers, my friend?  We don't, we train him or her ... and pray.

That's not true. At least around here they make sure that you are equipped with the abilities of a few hundred million years of evolution before they even let you near a car with a driving instructor. Sure beats training a thing that has no idea what it is doing - or why it is supposed to do it. Did they really have to teach you how to look around and make sense of what you see?

That didn't help us with chess and go. In a battle between engineering and the evolution -- in short term my bet is on evolution, and in long term on engineering.
Resistance is futile, robots will assimilate you AND your cat.

Evolution doesn't have anything to do with the ability of braking in time when a pedestrian jumps in your way in unexpected places while you're controlling a 1500kg mobile object at 38 mph. Or pretty much any other situation that we have to deal with when controlling a car. If anything, the instincts that evolution got us will make us behave inappropriately.
If anything, most of evolution taught us that it's best to run over any pedestrian who's stupid enough to run into our path - one less competitor on our hunt for food! In that respect, most autonomous systems are already better than that before they even start training!

Indeed? So you needed someone to teach you how to detect the pedestrian jumping your way? You did not have a naturally evolved image processing system (among other things) in that grey matter between your ears? And a neural net that is by orders of magnitude smaller and with only a tiny fraction of the training time (no matter how you measure it) will do the job better?
I wish I could share your optimism.

I did also say at 38 mph. Typically a human moving at 38 mph through pretty much all of evolution was only seeing one thing, and that is the ground he was about to hit - not the kind of stuff going into the genes except into the genes of the onlookers. If evolution taught us anything it is that moving at 38 mph is fatal.
Now, of course, if your forefathers were running through the jungle they certainly did learn to react to a creature moving into their path. But, depending on the number of claws and teeth (or raised clubs) of that creature, stopping might not have been the preferred type of reaction.
I'm not saying that this is not an important bit of information when deciding that you need to slow down when something moves into your path, but it's also so much different from the evolutionary training, that the lesson learned can be pretty much reduced to saying that: if something moves into your path, slow down. And that is trivial to learn for any autonomous system, no matter how small.
In case of the accident, this raises the question why the cars sensors did not detect the woman, or identify it as an actual obstacle. Apparently the driver didn't either, or at least not in time, and his millions of years of evolution didn't help him in any way there. But the car's systems should have been able to both detect the woman (using the LiDAR sensors) and react to it as well (thanks to super-human reaction times). The investigation should focus on these questions.

I would say your well thought out logic is interfering with an ill-thought out rant.

That's exactly the reason why I am going to stick to driving my car myself rather than handling it over to AI. If a fool jumps in front of my car suddenly, I am going to run over the guy. I don't want the AI to brake hard and send my head to the steerwheel.

Home sapiens have only been around 200k years. We have only been using faster than human modes of transportation, starting with horses(?), for around 6k years. Regardless of all that, with a human, you are still counting on that person's physical limitations (age, reaction time, visual acuity, etc), their attention span, and the skills they have acquired to be a good driver. With an AI you have (hopefully) a system that pays attention 100% of the time, can aggregate and build upon past experiences of multiple individual systems, and can actually have sensors that surpass what humans can see. Look at it this way, think of the quality of cars before robots were used in mainstream production. The tolerances were able to be tightened and quality has improved by using them. Over time I would think we would get to a point where cars could talk to each other and even help avoid accidents all together.

That's very nice, but falls short of the mark.

Quite so. Since when is any AI capable of forseeing future events by using experience? So far, only we have been able to do that, not even the closest relatives.
Here we have stretches of highways without any speed limit. I really enjoy a ride at the maximum speed my car is capable of, usually while having a good eye on what happens on the lanes to the right. Most poeople see you coming and wait until you have passed, but there is always a 'Kamikaze' who pulls out right in front of your nose at a fraction of your current speed. A AI would not react to them until they actually pull out, but then it may already be to late. How do I notice them ahead of time? I don't know. It must be something in the way they behave prior to changing lanes, but I notice them and hit the brakes before they actually do it.
