I realize that the suspension isn't unique to Tesla, but over-the-air software updates seem to be. It irks me to no end that I'm told that my Infiniti can't be updated to even work properly with my iPhone, much less the fact that they want to charge for gps map updates that are essentially free from Apple, Google, Microsoft, etc.

I'm pretty sure map data is expensive and those companies license it.

I realize that they license it. I dispute that it's anything but a cash cow for those companies that charge $100-$300 for map updates that many other companies make available for free.

I've purchased licenses for multiple software packages and at the scales that these car distributors work at, it's ridiculous to think that their actual gps data costs aren't nominal (ie, pennies) per vehicle.

"However, to improve things further, we provided an over-the-air software update a few months ago to increase the default ground clearance of the Model S at highway speeds" I know this is not specific to Tesla, but it's still really cool. :)

Yes. My '13 Prius V MP3 player doesn't properly randomize tracks from my flash drives. Apparently no one at Toyota tested their player with a 64 gig thumb drive with ~840 directories.

I doubt Toyota will ever retro-fix the obvious software flaws. Tesla however sounds like they get it. Although many of us won't be buying an $80K vehicle any time soon, I expect that these kinds of innovations will trickle down to the mass market as people start to become dimly aware of the benefits.

Hey, people might even start to ask why all cars can't be made as survivable as a Tesla S.

This is written in a semi-sarcastic/ passive aggressive tone to get across the point of how safe their vehicles already are. Very cheeky of Elon and his team.

Let's not forget that Tesla recently issued a recall for 29,000 charging adapters because they would overheat and catch on fire. http://www.nytimes.com/2014/01/15/automobiles/citing-chargin...

Come on dude, you make it sound like these things we're catching on fire all over the place - "... the number of incidents remains small, and Tesla’s review to date points to the building receptacle or wiring as the primary cause of failed NEMA 14-50 adapters, the company has determined that a voluntary recall is appropriate as a precautionary measure.”

And lets not forget how astonishing that is in light of what many other car manufacturers[0] do when they find issues that effect millions of their cars in a much more dangerous way. The fact that even with that issue, their safety numbers are through the roof and their number of incidents are way under the national average, and they still willingly and transparently issues a recall, I count that as nothing but a plus for Tesla.

I'm sure there are strict security measures and a rigorous testing regime in place, but still the idea of some anonymous engineer being able to push an over-the-air update to my fast moving, two-ton lump of metal makes me a little nervous. (Tin foil hat mode) Imagine the implications of some malicious third party gaining access to that process.

Agreed, what are the chances that there is no vulnerability (say buffer overflow attack) that allows a black hat to get into the system?

Or even an "oops, I pushed that update to production instead of test"

That it sounds like it was written in Slashdot passive aggressive style: rather than just directly saying it was an extreme scenario, they used list of somewhat-hyperbolic-but-way-more-so-if-you-know-the-jargon descriptors of each element of the crash.

Part of me thinks that they are deliberately passive aggressive, like, "I can't believe people don't believe yet that our vehicles are safe, fine, let's just go all out and shove it in their face."

Only part of you?

I've worked in industrial process systems where firmware is pushed out to millions of devices. The process is pretty rigorous - first the engineering team develops a candidate build, they run it through full regression and acceptance. Once it passes all the various code quality tests (coverage, static analysis, etc...), it's signed. Only code which is signed can be run on the production bootloader. The process required to sign a firmware image requires M of N people to come together with their credentials (hardware keys) to have the HSM (Hardware Security Module), sign the firmware.

The actual roll out of the firmware is of course staged - in Tesla's case, they likely roll it out to all of their employees teslas for a period of time, and then to a candidate group, and eventually everyone.

The team that actually pushes the firmware, is completely separate from the team that builds, and signs - they have a fairly detailed set of procedures that ensures a quality push, which is their entire focus.

The likely difference, is that the process I described, usually took 4-6 months after the code was completed, whereas Elon Musk/Tesla can probably spin it around in 4-6 weeks.

"An ode to passive/aggressive and hyper defensive writing" Did this remind anyone else of when the smartest kid in the room was forced to apologize for something and you got the classic non apology apology? Keep building great cars Elon and changing the world. Understand that we understand that there will be (I almost said bumps in the road) and that no one expected you to be perfect in every way from the very beginn…

Yes which is childish and pathetic. Car safety should never, ever be joked about. People's lives are at stake.

John Cleese doesn't agree:

    “Too many people confuse being serious with being solemn.”
He expands:

    Now I suggest to you that a group of us could be sitting around after dinner,
    discussing matters that were extremely serious like the education of our chil-
    dren, or our marriages, or the meaning of life (and I’m not talking about the
    film), and we could be laughing, and that would not make what we were discuss-
    ing one bit less serious.
    Solemnity, on the other hand, I honestly don’t know what it’s for. I mean,
    what is the point of it? The two most beautiful memorial services that I’ve 
    ever attended both had a lot of humor and it freed us all and made the ser-
    vices inspiring and cathartic. But solemnity, it serves pomposity and the self-
    important always know, at some level of their consciousness, that their egotism
    is going to be punctured by humor. That’s why they see it as a threat. 
and as an example:

    “Graham Chapman, co-author of the "Parrot Sketch", is no more. He has ceased 
    to be. Bereft of life, he rests in peace. He's kicked the bucket, hopped the 
    twig, bit the dust, snuffed it, breathed his last, and gone to meet the great 
    Head of Light Entertainment in the sky. And I guess that we're all thinking 
    how sad it is that a man of such talent, of such capability for kindness, of 
    such unusual intelligence, should now so suddenly be spirited away at the age 
    of only forty-eight, before he'd achieved many of the things of which he was 
    capable, and before he'd had enough fun. Well, I feel that I should say: non-
    sense. Good riddance to him, the freeloading bastard, I hope he fries. And the
    reason I feel I should say this is he would never forgive me if I didn't, if
    I threw away this glorious opportunity to shock you all on his behalf. Any-
    thing for him but mindless good taste.
    (He paused, then claimed that Chapman had whispered in his ear while he was 
    writing the speech):
    All right, Cleese. You say you're very proud of being the very first person 
    ever to say 'shit' on British television. If this service is really for me, 
    just for starters, I want you to become the first person ever at a British 
    memorial service to say 'fuck'.”

Nice move on their part. I think while the Tesla may be less fire-prone than other cars, Musk exaggerates it:

"The odds of fire in a Model S, at roughly 1 in 8,000 vehicles, are five times lower than those of an average gasoline car..."

What matters is the miles driven by cars, not the number of cars on the roads. It seems likely that other cars are driven longer distances, and Tesla cars are probably used by many owners as a second car.
