NASA from what I understand, got all their information from what Toyota
chose to furnish. In the Oklahoma trial, expert witnesses actually got
source code to analyze.

OK, I even have a pdf, and I gave a link to it here last year, of an internal report
that describes the bug, google

I have just read these links you gave, and indeed from Barr's POV it is crap.
But we must not forget ECC RAM and stuff like that is not that common in embedded systems.
It must be clear to anyone that 'electronics' will not make a car safer (than simple mechanics).
In airplanes you may have 3 the same systems and an arbiter so to speak, if any system disagrees...
majority vote, but even then, no 100% guarantee.
If Mr Barr looked at my latest code he would probably die drowning in tears, my PICs have only limited stack space,
and lack some of the features he considers necessary...
Where is the limit?
I do not want to justify Toyota, neither the F*ckupshima nuclear plant design, but hey, life goes on.
Buy an old Mercedes diesel and you are OK...
If it is anyway like the environment I used to work in, then there is anincredible time pressure
to get things working, not sure how many man hours Barr spend testing allthat stuff, but think about it.
We can learn from Mr Barr's report though, I often worry about stack depth.
But really and honestly, I would drive a car that was controlled by a controller I designed without all those features Barr says it 'needs'.
Something is up to the driver too.
For sure cars should not start accelerating by themselves, and coffee should not bee too hot.
(Mc Donalds lawsuit, milions?) But would a decent driver not know a few tricks how to stop it?
I have driven cars that .. well you do not want to know.
US lawsuits... come to think of it : Should not have NSA been listening to the controller?
Now you get internet, maybe remote software updates by the factory while you are driving?
Do you think things will get better?
LOL
