    As hard as it may be to remember these days, it is possible to communicate without the Internet

    We're talking about systems here, not intersocial communication.
     
    If you air-gap a machine, then you need to hire people to maintain the machine locally. This just does not scale.

    especially when that communication need only be local

    For instance?

    What use is an air-gapped machine? How do you communicate, how do you control it? Build your own physical network infrastructure (preferrably with blackjack and hookers)?

    Let's go back to where this started, shall we?

    Sure.

    An AC claiming to be Ethanol-fueled stated that a manual transmission is safer when your brakes get hacked because you can still engine break. He did this by giving the unfortunate example of shifting into 1st. He didn't explicitly state he would shift directly into first(*), and I took it to mean shifting into 1st after passing through all the other gears (yes, he still should have written 2nd). You took it as shifting directly into 1st, but even if that was his intention, it was simply an invalid example of a largely valid principle: you can slow down a manual transmission by engine braking.

    And you can slow down an automatic transmission by engine braking.

    Anyhow, I took your ambiguous statement as pertaining to engine braking (which, if dangerous, would refute his argument) rather than to switching directly into 1st gear (which is dangerous but missing the point). And now you're accusing me of "intentionally misquoting" because I didn't automatically assume you missed the point (which, as it turns out, you did).

    Ehm, i maybe accused you of intentionally misquoting because..

    (*) which would indeed be a very stupid thing to try at highway speeds though it won't kill you at any speed;

    ...because here it goes again. You still try to make it look like I had said shifting into 1st gear would kill you, you still didn't understand what i was originally saying, you're looking dumber and dumber every second.
     
    Since we're just in the process of going back to the start, let me quote myself, again:

    Good luck with that at any speed which would have the potential to kill you

    Lets systematically chop this sentence into pieces which you can try to understand one at a time.
    Perhaps it's most useful to start with this one:

    speed which would have the potential to kill you

    This establishes the notion of a velocity at of above which you can potentially, or likely, die in a car. 5 mph is not one of them. 50 mph is one of them. 100mph is clearly one of them.
    Do you understand so far?

    Now for the other part:

    Good luck with that at

    As hopefully becomes obvious now, all i was saying is that it will be hard shifting into 1st gear at such a speed.

    Did you finally get it now?

    at around 40 km/h or less, assuming you succeed to do it, it might deal some damage to the gearbox, but it's unlikely to kill you.

    Yes, no shit sherlock. see above for an explanation why you're utterly and repeatedly missing the point.

    It wouldn't matter if the transmission blew up too. The entire point of the situation or hypothetical is to keep your life at the cost of the car instead of losing both

    My point was, if the transmission blows up, you're losing the ability to engine-brake, is all.

    Good luck with that at any speed which would have the potential to kill you

    The point of downshifting is to go from a speed which can potentially kill you to a speed that most likely won't kill you.

    Yes. Better have free way ahead. However, the GP sounded like shifting right into 1st, which obviously isn't possible at considerable speed

    Or turn off the ignition.

    Great idea. Just don't turn the wheel, because the steering column locks. Hope you're dying on a straightaway!

    Actually, the cars I know won't engage steering lock unless you actually pull out the keys. Things might be different in the USA, admittedly.

    No, you're wasting gas that way, since you still need some to keep the idle rev. Non-ancient cars will actually shut off fuel injection when gravity happens to temporarily become 'fuel'

    On the very limited number of cars that support this feature, it will occur regardless of whether you're in neutral or not.

    No, and LOL. What do you think happens when the car is in neutral and you shut off the fuel?

  11. Re:Efficiency. on Who Is Liable When a Self-Driving Car Crashes? · · Score: 1

    With some practice, you can time the gas and the clutch just right so that the wheels will lose traction ("spin") when starting yet the engine doesn't go to insanely high RPM ("revving").

    That does not work with lower-hp engines. Please find out at what revs you get the highest torque out of common gasoline engines.

    And this can even be done with a very modest engine

    No.

    all that's needed is mastership of the pedals...

    ...and the way you keep talking about "mastership of the pedals" makes me suspect that this is a skill you very recently acquired. Otherwise you would kind of realize it's no big deal, and fairly easy to master.

    If you can't do this, then I also wouldn't want to be close behind you when you attempt to start on a slope.

    This is ridiculous. Again, like it was a big deal to properly start on a slope.
     
    You keep basing your arguments on the wrong assumption that i somehow wasn't able to properly drive a manual transmission car. It really does not make sense to keep insisting that was the case. After driving all kinds of cars and motorcycle, and having done nearly 200,000 km on the Autobahn, I'm pretty sure I have 'mastered the pedals'. But thanks for your amateur insight.

    Government takes out my brakes? No problem, shift into first and engine-brake going 10 mph down the hill.

    Good luck with that at any speed which would have the potential to kill you

    Any chance you're confusing engine braking (using the air that is pumped through the motor to dissipate energy) with applying the handbrake? Now, engine braking in first gear at high speed is likely to destroy your engine in addition to not being very effective, but I wouldn't think the chances of it killing you outright are that high.

    At this point i'd like to recommend you practicing basic reading comprehension. No, pretty sure i don't confuse engine braking with the handbrake. Me not mentioning handbrakes at all gives a slight clue regarding this matter. My point is, you won't even be able to get the 1st gear engaged at any considerable speed (and if your do manage it, you destroy the engine (as you point out, supporting my point), likely destroying whatever was dissipating the energy before.

    Car doors can usually be opened from the inside even when locked.

    ...except when opening them against a significant pressure gradient. Car doors often cannot be opened in a sinking car, whether they are locked or not. And even if they can be opened, leaving them alone and going for the windows gives a better survival chance.

    So, you agree with me on the door matter.

    Disclaimer: i drive manual transmission too, but for none of the reasons you mention. My reasons are: a) simpler/more robust design (i.e. one less part which can fail fail), b) more control, c) avoid ridicule

    You're driving manual and don't know how to engine brake? I got some ridicule for you right here. In my home country, you can't even pass the on-road driving exam if you don't demonstrate routine use of engine braking.

    Uh, i was under the impression that i'm confusing engine braking with hand braking, now i'm not to know engine braking at all? You're not making much sense here, my dear friend. If you're representative for people in ``your home country'' then i'd much rather not drive there, thanks. I can go faster and safer here, anyway.
