I honestly don’t know if I would have seen and avoided that, it came up really fast. And based on the video it looked like a cardboard box or something not worth avoiding until it was within 2-3 seconds range.

It was at least six seconds between the co driver pointing it out and the car hitting the object. The screen shows 77mph, which means he saw it from approx. 200m distance. Anybody would at least be able to prepare or slow down in such a situation.

Earlier quoted context omitted.

The issue with ‘driver in the loop only for emergencies’ is that it’s harder for someone to be prepared to react only occasionally (but still promptly and correctly) when outlier behavior happens, not easier. For automated tools like CNC machines, there is a reason it’s just ‘emergency stop’ for instance, not ‘tap the correct thing we should do instead’. But doing an e-stop on a road at speed is a very dangerous acti…

And you don't even know until it is too late even if you are paying attention. Suppose you see the obstruction well in advance. You expect the car to change lanes. You get past the point where you would have changed lanes but there's still time. You aren't yet aware that the car is missing the obstruction. A moment later you are much closer and make the judgement that the car is making a mistake. You grab the wheel b…

Yeah, in many ways the only way a human can know for sure that it’s not seeing something is past the point of no return/the absence of action, which is always hard.

A friend of mine who loves Tesla watched this video and said "many humans would have hit that". I feel we'll be hearing a lot of that excuse.

Well, I have to admit that your friend has a point. Humans are bad at reacting quickly and correctly to unexpected situations, and some debris large enough to damage your car showing up from out of nowhere after several hours of boring driving along a largely straight highway with little traffic is definitely one of these situations. But a self-driving system worth its salt should always be alert, scanning the road ahead, able to identify dangerous debris, and react accordingly. So, different pair of shoes...

I wouldn't. And I'm not that great a driver. The Tesla should be significantly better than me.

I thought the title meant the software crashed, but it was the car that crashed: "They didn’t make it out of California without crashing into easily avoidable road debris that badly damaged the Tesla Model Y ... In the video, you can see that the driver doesn’t have his hands on the steering wheel. The passenger spots the debris way ahead of time. There was plenty of time to react, but the driver didn’t get his hands…

There's sort of an analogous conundrum with Airbus-style automation: the system has various levels of automation and protection (e.g. preventing you from stalling the plane)

And then when something goes wrong, you are unceremoniously handed a plane with potentially some or all of those protections no longer active.

As an analogy, imagine your FSD car was trying to slow down for something, but along the way there is some issue with a sensor. So it gives up and hands control back to you while it's in the middle of braking, yet now your ABS is no longer active.

So now the situation is much more sudden than it would have been (if you had been driving the car you would have been aware of it and slowing down for it youself earlier in the game), you likely weren't paying as much attention in the first place because of the automation, and some of the normal protection isn't working.

So it's almost three levels of adding insult to injury. Potentially related discussion: https://news.ycombinator.com/item?id=43970363

> Tesla’s EV business is in decline and the stock price depends entirely on the self-driving and robot promises I don't think that's right; I think the stock price entirely depends on people seeing it a vehicle to invest in Musk. If Musk died tomorrow, but nothing else changed at Tesla, the stock price would crater.

I actually think the stock price would go up. His detour to fascism and megalomania has chased off tons of liberal environmentalists like myself that are the target audience for electric cars. I cancelled what would have been our replacement Tesla when he was implying on Twitter there can be good reasons for sneaking into the speaker of the house’s house and hitting her husband in the head with a hammer.

A thorough analysis of the materials/energy reality we inhabit could lead one to make a similar decision for environmental reasons alone

I don't love Tesla (though I would like an electric car). I don't think it's unlikely that someone driving could have hit that or caused an even worse accident trying to avoid it.

However, I'm sure a human driver in the loop would have reacted. The driver sitting there watching a machine do it's thing 99% of the time and being expected to step in to save that situation though is a horrific misreading of human nature.

"is a Level 2 driver assistance system that requires constant supervision by a human driver" - the reason for human supervision might have something to do with uncommon situations (debris in road being such a situation). Elon's estimates have always been off but it is irresponsible to see an obstacle up ahead and assume the computer would do something about it while the driver and passenger debate on what the said ob…

Level 2 is very dangerous because it's so good that humans are only needed in emergencies...

I assume you spotted the problem? Or are you saying you missed it?

Tangentially - If you as a European happen to drive on US highways, you will noticed that they are heavily littered with fallen cargo, aluminum ladders, huge amount of shredded tires and occasionally a trailer without a towing car... It has been so bizarre for me to observe this. Nobody is cleaning that?
