Is that a loving car flying through the air?
Kinda looks like one doesn't it? It might be a big container full of explosive liquid or gas though. Often the welds at the top/bottom are the weakest so they launch into the air like rockets (or blow their lid) when they go.

IMO the Japanese response was even worse than the god-awful retarded repair job. The US base at Yokota had the plane on radar, had a helicopter at the crash site within 20 minutes, and rescue teams ready to deploy... and then someone in the Japanese government told them to stand down. The Japanese responders didn't even try to reach the site until the next day, they spent the first night pitching tents in a village 60 km away. Meanwhile a whole bunch of people who survived the initial crash are bleeding and/or freezing to death, with only four survivors by the time Japanese rescuers actually arrived.
drat, that's hosed up. Hundreds of people died so some random dipshit politician could save face.

I don't have a clue so this is an honest question: what is the current state of software control in modern cars? Do they have control over the engine and braking system such that they could accelerate you down the street and plough into oncoming traffic? If so, loads of us are trusting software with our lives.
They do. Toyoto famously killed several people by doing a terrible job of it. It's such an unbelievably shoddy piece of work it's a good fit for this thread! :v:

That's too vague a consideration though. Drill down a bit. The important thing to ask is why do people trust these control systems in the first place, and how applicable are those reasons to other problems? Well, the degree of trust is a function of their simplicity, predictability, constrained feature set, well defined operating conditions, and the exceedingly high quality standards they must meet.

All those aspects of the system are related. More complexity multiplies - not adds to - the difficulty of making the system work safely and reliably across its various use cases. You need to test most combinations of features and subsystems together or it becomes more and more likely that little Timmy is going to turn into a beef patty due to some oversight. So this burden can very quickly become a profound one.

I work with people who develop these systems and they say just the extra verification work needed to quantify and guarantee safety in their systems adds two extra years to the development time and millions to the cost. These are relatively speaking very simple systems too. Self-driving on the other hand maxes out every single one of those considerations to their craziest levels, multiplying up the verification requirements to a degree that I can hardly even describe. Making something safe despite unlimited complexity, imperfect information, unpredictable conditions, a massive feature set... it's a nightmare project. Making it work at all is the lowest bar possible and even that's a really drat tough one to clear.

When it comes to autonomous vehicles, I'll be happy if they perform as good as humans. Performing better would just be icing on the cake. Over 30,000 people die on the roads in the US each year, the bulk of which is a result of driver behaviour. I wonder how many deaths the computers will be allowed before they are considered a failure?
If they're only that good though, it could wind up being too expensive or publically disasterous. It's no longer merely someone dying using our product, but our product failing and killing the customer as a consequence. If that happened often the product's life could also end up coming to an abrupt end.

Also consider that for each fatal crash there are 170 more crashes that wreck the car but don't kill anybody, totalling to more than five million. That's a lot of crashes to be responsible for. Repairs, new cars, hospital costs. All our fault. I don't think we could release a product with that kind of risk without it being the world's biggest albatross around our necks.

Don't get me started. I've been a part of discussions where department heads were actively pushing to add a permanent hardware backdoor in our security-critical product to reduce risk. The understanding is just not there at a high level in a lot of non-software-specialised companies.

Deeply unfortunate that the public takeaway from Toyota's criminally negligent software design seems to be "user error". That's their legal department's defence that you're mistaking for truth. Don't know why you would believe them.

In court, the software was examined by an embedded software expert. His conclusion, having examined their software for 20 months, was that the "unintended acceleration" was not only a possible cause but definitely the cause. Why, because they totally hosed up every possible aspect of their software. It was embarrassingly and shockingly bad work throughout, with every single steroeotypically terrible design choice you can imagine. Untestable, unmaintainable spaghetti code. No MISRA compliance. Thousands of warnings in released code. Unintended memory corruption. No ECC on the hardware. Thread safety violations. A total lack of redundancy. 11,000 global variables.

This is the kind of joke level garbage we embedded software people laugh about at lunch, except this time it was linked to whether people lived or die. Toyota hosed up their software and it killed people, that is the undeniable truth.

Another factor with shrinking silicon geometry is that it affects reliability. Bit flipping errors happen more often, it's more sensitive to temperature, lifespan is reduced etc.

On the last 45nm chip I worked on, every 64 bits of flash memory had another 8 bits of storage purely for error correction codes and enabling it was mandatory. 1-bit errors are now expected to happen frequently enough they're part of normal operation. The SRAM also had the same ratio in parity bits to detect errors. After all it's not good if your 32-bit throttle control variable flips a high bit and suddenly has 2^31 added to the value and you don't know about it. :v:

The actual story is that a 14 year old who liked to play with electronics was too brown and got arrested at school for his case full of wires and circuit boards.

Because racism is physically impossible and can't happen, a conspiracy narrative formed where he was extremely suspicious and his family were radicalising him like a ninja turtle etc.
