Toyota Black Box Data Is More Closed Than Others'
wjr writes "Many cars these days contain black boxes that record information (speed, accelerator position, etc) and can preserve information in the case of an accident. Ford and Chrysler say that they use 'open systems' so anyone can read out the data; General Motors has licensed Bosch to produce a device capable of reading its cars' black boxes. On the other hand, Toyota has only a single laptop in the US capable of reading its cars' black boxes, and generally won't allow the data to be read without a court order. Honda seems to have a similar policy. This is emerging as an issue in the investigation into unintended acceleration."
I prefer having breaks, steering, and not having an accelerator stick to the floor.
Wouldn't it be grand if the guys who hacked Ubisoft's latest game [slashdot.org] took on this challenge instead?
It would be nice, but it's impossible. They'd have to be some sort of elite uber-hacker to even attempt such a challenge.
Absolutely impossible.
Not a hope in hell.
Can't be done.
their first line of defense is security by obscurity
I think their first line of defense is knaji, hiragana, and katakana.
That leaves over 97% of the world out of the loop.
I don't think a hacker really gives a shit if a variable is named "carSpeed" or named " " ... well, unless the hackers are the same people that made /.
By now you should know how this routine usually goes.
No, there aren't any websites like this. All Sites that had lists and pictures of disected dashboards that showed those chips have been pulled off the net. That alone should be proof that those rumours are true, for what other reasons would someone be intrested in covering it.

Will Toyota stop at nothing?!
Man blir trött av att gå och göra ingenting.
And when they tote up the "100 million lines of code", they're probably counting the operating system and packaged apps they bought to play media. If the dash panel entertainment display computer is running Windows Mobile I bet that gets you to 100 MSLOC right there. I find it hard to believe there's more than a million lines in the application level code written custom for the car, and hopefully under 100K or even 10K for the microcontrollers running the critical systems. More than that would be impossible to verify to reasonable safety standards, and the cars would be doing crazy things like accelerating for no rea- oh, wait.
You can ignore the spaces in code, those aren't variables...
I'm really curious to see an analysis and some code samples from you where you planned and implemented space variables...
I think we can keep recursing like this until someone returns 1
so it's probably written karuSpeedu or something...
how long until
I've got this CISC chip, has just 2 instructions: PHW and CLS.
Technically, I can do it in one line, but I like a tidy screen.
