Much of the NASA report's review of Toyota's source code ("Appendix A") was redacted. Some entire pages were redacted. I got to see the unredacted NASA report, but only in an RF-secure room with no Internet and no phones (and no metal, belts, watches, or paper in/out). And I can't tell you what I saw there. Little of that is proprietary but lots of it would be embarrasing to Toyota.
