Toyota learns the tyranny of software complexity

As a former auto put over, I feel sorry for Toyota, I really do. To me it seems like their exceptional error was just believing their stuff has to be superior and can never leave. Unfortunately, as cars get more and more complex, horrid problems like these unintended acceleration events are dependable to occur. The rocket scientists that designed the Space Alternate thought they were infallible and hot stuff too , until the ridiculous complexity of the gang caught up to them and the inevitable disasters started occurring. Perchance Toyota did the same kind of oversimplification of analysis that NASA did .

And into it, a modern car is a wickedly complex device. Dozens if not hundreds of microprocessors are all whirring away, and they must en rapport of the CAN bus to sense and control critical vehicle functions. The guidance has been concentrating on the reliability of pollution control functions, since it never occurred to them a car would get so complex its safe keeping would fail in these subtle ways. When I was an engineer at Ford Motor I would often consider engineers exclaim “That is a million to one!” when I unmistakeable out some subtle failure mode. I would respond, “Strategic, and how many cars does Ford make every year?” After they hemmed and hawed and admitted we were shipping 6 million vehicles year, I would ask which 6 people they wanted to put an end to, and what would they say to that person’s mother and loved ones?
