Barr's ultimate conclusions were that:

  • Toyota’s electronic throttle control system (ETCS) source code is of unreasonable quality.
  • Toyota’s source code is defective and contains bugs, including bugs that can cause unintended acceleration (UA).
  • Code-quality metrics predict presence of additional bugs.
  • Toyota’s fail safes are defective and inadequate (referring to them as a “house of cards” safety architecture).
  • Misbehaviors of Toyota’s ETCS are a cause of UA.
