This is astounding to me: Would you get in a car if you knew that core parts of design were not designed at all, but kludged together, ignoring established engineering practice? That, because of this, important chucks of the car could never be tested, so no one knew if they actually worked or not, and were subject to failing in ways that were not only unpredictable, but unreproducible? That the problem was so bad that people have actually been killed? Oh, and that the car manufacturer actively lied, repeatedly, to cover the whole thing up?
According to the testimony of experts who reviewed the Toyota's source code for the software embedded in their cars as part of a lawsuit regarding problems where their cars would accelerate out of control, that's exactly what was going on. If you know anything about software engineering, the highlights of that testimony will likely send the same shiver down your spine that it did mine.
