    Come on, give me a break. It's not all about instant death, it's more often about about quality of life.

    A few years ago I inexplicably developed asthma in Northern California (I have never had a single allergy, etc in 40 years). The doctor said she had seen a huge number of the same cases due to major fires south of San Jose that year (so bad some days you could see a haze in the air 50+ miles away). And I have never had the symptoms since (well, actually - one time - hanging out in a bar in IL before they instituted the smoking ban... so it's pretty clear what triggers it...)

    Well, then I respect what you do and the risks you take, but I still don't agree with your overall assessment of car fires :) But yes, I didn't mean to withhold information, and the fire was initially started on a hot summer day when gasoline vapor ignited from a spark while my Dad was refilling the lawn mower (causing him to drop the gas can, and there ya go...) And I don't see why car burning would imply the tank has to explode - clearly there would be nothing *under* the tank burning, so a car's engine/upholstery, etc on fire with just a concrete slab underneath the car (and therefore the tank) doesn't mean the tank has to get *that* hot.

    A gas tank in a burning car will heat up. If it reaches boiling point, it will explode, or violently burn the fuel in the tank.

    Boiling point of a liquid just makes it a gas (which of course increases pressure), but in no way does that mean a container undergoing high pressure has to explode. As I'm sure you know, propane containers are under high gas pressure as well, since their boiling point is like -40F - but they are designed for that pressure (but of course, increase the temperature and therefore pressure beyond its limit and who knows, PV=nRT, etc). And while that gasoline might have also been heated to around its ignition temperature, it also requires an oxidizer - as long as the tank can withstand the pressure it's probably not going to explode...

    And yes, from my previous comment the NFPA (which as a firefighter I'm sure you know) article said while ~10% of car fires involved the gas tank (my original point!), those of course did involve burrning/exploding tanks and were much more likely to be fatal...

    Anyway, I still stand by my point that gasoline tanks (and their placement - ie. not too close to the engine, and not behind the rear axle/in crumple zones) in new cars are very carefully designed for safety, and lithium battery packs not so much yet, so there may be some pretty unexpected electric car incidents. I would guess as a firefighter you'd agree with that? But still, if I had $80k lying around and wanted a Tesla I'd feel perfectly safe driving one - unexpected does not imply inherently dangerous, and the number are way too low to make generalizations. And I'm sure, like ICE cars (see: Pinto) much will be learned and they will become safer with every new incident...

    Why on earth would you bother making bunch of wrong assumptions about *my* anecdote?

    No, the garage was packed with shit, several other items with gasoline in them (leaf blower, snow blower) literally exploded, and the fire was so hot it warped some glass on the house 30 feet away. There was almost nothing left of the car except the bare metal frame. And the garage definitely "burned down", there was no roof left by the time the firefighters managed to contain it.

    And the firefighters themselves said they weren't that worried about the gas tank exploding, since automobile tanks are designed to withstand high heat and pressure in the tank, ie. it was NOT the exception but the rule. Unless the tank it punctured the gas in it was unlikely to ignite. At least go look it up instead of making it up - the majority of car fires (even in "on and running" cars) involve the engine compartment (gas in the lines, oil, etc) and the upholstery, etc, but not the gas tank itself (I saw a stat on NFPA that quoted ~10% of car fires involve the fuel tank). Which was my point in countering the comment "the gasoline is 99% of what is burning and not really the car itself", which is false in more cases than not.

    But you probably know more commenting on an anecdote without any information than firefighters who see this all the time or associations whose job is to minimize fire risks, of course...

    You do realize the gasoline is 99% of what is burning, and not really the "car" itself, right?

    No, that's not necessarily true. my parents' garage burned down a couple years ago and totally destroyed a car inside - but the gas tank survived. The car was a shell, every bit burned down to the metal frame, except for the gasoline in the tank. Gas tanks have had 100 years of engineering to help prevent fires. Lithium batteries in cars are a completely new issue, and are going to have their growing pains.

    Personally I agree with the point that there is not enough data to support Lion battery cars are any more dangerous than ICE, but you have to admit the latter does have a lot more data and engineering to ensure safety...

    You couldn't have read much Heinlein to have that impression. Some of his stuff was brilliant, some (the later stuff) was just weird and pervy, but one thing he generally didn't do was push a single socio-political agenda in his works. In fact, if anything, he very specifically explored about a half dozen over his various novels and short stories.

    I find this to be somewhat laughable. Robert Heinlein was entirely serious about the message that the story delivers. That only those who serve in the military and commit violence in the name of their country should truly be considered "citizens" of the country.

    Actually, you have just proven you never really studied the author (or at least understood what you read). The book even says (and Heinlein has expanded on it in interviews, etc) that the service did NOT need to be military, but could take many forms of volunteer government service. His message had nothing to do with requiring someone to "commit violence in the military", it was about feeling a moral responsibility to your county if you want to choose its leaders (or become one).

    I don't even want to think about what a 200mph+ DOT tire costs.

    Especially since the DOT doesn't even rate them ;) They rate up to Y (186mph) but manufacturers tend to use "ZR" (which is unofficial) for tires that can go beyond that. Though the Veyron's tires aren't rated at all since there is no point, they are custom made for that one car and cost $40k for a new set (and not only that - they recommend replacement of the tires every 2500 miles and of the WHEELS every 10,000 miles!)

    As far as the cost of regular tires, I guess it depends on what you mean by "regular". I just put new Michelin PSS's on a 997 C2S and they were cheaper than the "regular" PS2's I had before. $1200 to replace all 4 from tire rack, that's actually pretty cheap for ZR tires of that quality...

  11. Re:Impressive. on Tesla Model S Can Hit (At Least) 132 MPH On the Autobahn · · Score: 1

    132 MPH isn't THAT ridiculously fast, but it is certainly fast enough that you shouldn't be doing it on standard production tires, even the ones rated for high speed, because they aren't rated for that high speed for any length of time ... or even ... say hitting a reflector on the road.

    Depends what you mean by "standard production tires". Production tires like Michelin PS2's/PSS's are most definitely rated for over 132mph for decent lengths of time. They are stock on 911's and Ferrari's that people use on the track all the time.

    I agree that there is no good reason the TPMS would be going off at that speed, though. He may have had them over/under inflated for some reason (or carelessness). The stock tires on a Tesla S are Y (186mph) rated Continentals, which would have no problem driving 130mph for a long time.

    If there was a TPMS warning for driving at 130mph for a couple minutes, there was clearly either something wrong with the tire (over/under inflated?) or the monitor...

If for some bizarre and horrible reason by normal operational procedure he was just the only person who knew these passwords, was fired, and said "fuck you", that would be one thing, and I'd agree with you. But he intentionally locked down the systems and refused to unlock them - both before and after he was fired. He even claimed that the reason was because "he didn't trust his supervisors with them".

    *Real* use of OpenGL and DirectX these days is all about the shaders, which get compiled and run on the GPUs. And even basic ops that are "builtin" to the drivers usually are using shader code internal to the driver (or microcode internal to the hardware/firmware).

    The people programming against the hardware shouldn't have to decide how much, if any, error is acceptable.

    Absolutely they should, and have been doing so with existing 3D hardware for a long time. It's just been more about 3D rendering shortcuts/heuristics/etc than faulty hardware. It's all about tricking the viewer's eyes and brain to increasing degrees, not reproducing an exactly correctly rendered 3D image... and until everything is raytraced that will continue be the case.

Even even with that, the "hardware decoding" is mostly happening on the GPU or other *programmable* video decoder hardware anyway.
