Is there a public version of their findings? Toyota hired Exponent to do an independent analysis of their electronic throttle and released that report to the public. It'd be interesting to compare Exponent's findings with the Barr Group. Exponent didn't find any plausible failure modes for the Toyota electronic throttle systems—their study looked very comprehensive, including a static code analysis and hardware-in-the-loop testing on the software side. They also did extensive hardware failure testing. It sounded like the Barr Group is claiming that the software was failing their quality tests, but it didn't sound like they were proposing a specific hardware or software failure that would lead to an uncommanded acceleration.
- ArkyBeagle 11y agoRight. No smoking gun. There were multiple scenarios described in which such a failure was plausible. The story is nowhere as cut and dried as in the Therac or the Arianne cases.
