From Appendix A, Software, of the formal NHTSA report:
In order to support the confidentiality of the 2005 Camry source code, the software was maintained within offices controlled by Toyota. The software teams traveled to these offices from NASA for study of the source code and Toyota documentation.
As noted, the NASA engineers performed the study on Toyota premises within an access controlled area. The NASA Software team/NHTSA/DOT had agreed not to remove Toyota intellectual property from this location, most notably software source code and design documents.
The focus in analyzing the Camry05 source code has been on a thorough static source code analysis of the ECM to find possible coding defects and potential vulnerabilities in the code.
Static analysis of source code is almost irrelevant in terms of finding deep logic errors. This is the equivalent of making sure that the code will compile and not much more.
Without full access to both the source and executable code in NASA labs and simulations, NASA's hands were tied behind their back and they never had a chance to truly evaluate the ECU software for hidden errors.
