  1. You may not have heard of this technology called autocorrect that changes words into other words seemingly at random, especially when the desired word is from a foreign language. Heaven forbid that I seek clarification.

  4. Why do you keep talking about the seatbelt locking? It's an irrelevant argument. They still always lock mechanically, no software involved. Your seatbelt isn't going to just unwind and let you smash into the dashboard unimpeded if the software fails to fire the airbag/pretensioner.

    What is controlled by software is the pre-tensioner that explosively shortens the seatbelt to pin you into your seat so you are better positioned for airbag impact. This absolutely must be integrated into the airbag system, and only electronic control allows accurate enough timing to make it effective.

  5. I don't know the stats on pretensioned seatbelt injury. The seatbelt pre-tensioner is part of a system; it doesn't necessarily kill people on its own, but it has the potential cause unwarranted injury and distraction. The SRS system as a whole definitely can cause severe injury and death. That's why they are always being improved. No one wants their explosive seatbelt tensioner to fire in non-collision conditions. It also needs to fire in coordination with the airbag to be effective; if it fires too late or doesn't fire at all it doesn't help. The SRS system needs to completely deploy in the correct order for the conditions within around 70ms of the first impact. Electronics are the fastest, most accurate, and repeatable timing system available.

    Isn't some simple mechanical fuse / switch sufficient for the airbag deployment system? Also, did old cars require SDM for the seatbelt to lock properly? Why are they changing mechanisms that have proved themselves?

    Isn't a carburettor and magneto sufficient to run an engine? The answer is yes, if you have no regulations, reliability and/or liability to be concerned with.

    Air bag systems have had software for literally decades, it's not new. Seatbelts still have mechanical locking. Electronically-controlled pre-tensioning is something else that has been around for decades now, and is part of the airbag control system.

    Modern air bags have variable deployment energy, which requires determining the severity of the collision, the weight of the occupant, etc. There are also side curtain and many other types of airbag that should only deploy when required, so the pitch, roll, and yaw, and even sideslip of the vehicle has to be known. Side curtain airbags need to deploy before the vehicle lands on its side, so software is required to predict when impact is likely to occur.

    Also, electromechanical systems can't self-check and diagnose themselves when there is a system failure. Air bag systems continuously monitor even the resistance of the igniter in the airbag to make sure it is correct.

    As vehicle manufacturers found out with carburettors and emissions regulations, mechanical systems quickly become too complex and unreliable to react to many inputs. There is no new passenger vehicle sold in North America that doesn't run its engine entirely from a computer. It's just that superior. Likewise with airbags.

  7. Because without software, seatbelt tensioners and airbags would deploy in many instances where and when they should not. These systems have to be very complex in order to not kill people inadvertently. Hence, self-diagnostics tests and the like. The state of the vehicle is modeled to determine the probability of a crash being in progress in order to make sense of individual sensor input.

    Google doesn't know it to be true because it is not true. Volkswagen ECMs are not over-the-air updated. They can't be. They don't have the physical hardware to do so. As a matter of fact, conventional ECU flashing is so risky it is highly recommended the car be connected to a battery charger to maintain voltage stability. Even better, a bench flasher (for aftermarket tuning). Even then, the flash is not always successful. When it is, it causes several codes to be thrown that have to be reset with a factory tool. This coming from someone who has byte-wise modified modern 2004+ VW ECU firmware with a factory-trained VW electronics specialist.

    Berkshire Hathaway owns 60 companies outright, taking them private through acquisition. Buffet didn't make his insane annual returns by controlling public companies, he did it by owning companies outright and shuffling capital from one to the other. There is only one tax return for 60+ companies, filed by Berkshire Hathaway.

    Berkshire's investment in public stock (Coca Cola, Wells Fargo, etc) is mainly through investment of insurance float by its subsidiaries.

    The myth that Berkshire Hathaway made its money by controlling publicly-traded companies is common. In fact, it is antithetical to Buffet's operating style. He is beholden to no one. If you want to share in his success you have to buy BRK.B and wait for long-term capital gains; you can't buy into his companies individually.

    It's pretty pointless to hook a neutral up to a delta-wired motor, code or no :D

    3-phase 4-wire feeds are used all the time for commercial power here in Canada. Either 208V or 600V depending on what is required. Single phases are circuited off for 208V/120V or 347V single-phase feeds, respectively. A neutral conductor is definitely required for this application, yes. 208V single-phase circuits don't use a neutral, since they use two of three phases as if they were single phase. Their "split neutral" would be ~60V with respect to ground.
