Les Jackson re-stated Edmund's conclusion that most cases of UA were caused by driver error.
Sean Kane and Joan Claybrook didn't like the conclusion, and in the Q&A period attempted to dismiss Edmunds. This is not surprising, as Kane and Claybrook are solidly on the side of the trial lawyers, and have an interest in showing that driver error is not the root cause. Kane mentioned tin whiskers as a possible explanation, despite the fact that NASA's analysis did not find tin whiskers as a failure mode that would cause un-detected unintended acceleration. Joan Claybrook stated that she finds it impossible that all those people, with their detailed letters to NHTSA, didn't press the right pedal.
