Reuters interviewed a former Tesla self-driving engineer and nine former data labelers who expressed skepticism about Tesla's "Full Self Driving" system. The publication also spoke with eleven independent traffic safety researchers who share concerns about the technology.
Current and former Tesla employees involved directly in FSD development do not endorse the system for widespread deployment. Data labelers, who prepare training datasets that teach neural networks to recognize road conditions and obstacles, reported reservations about the quality and completeness of the data feeding the system. Their firsthand experience with raw footage and labeling protocols revealed gaps in edge case coverage. Coverage of rare but critical driving scenarios remains insufficient for safety-critical deployment.
Traffic safety researchers emphasized that FSD lacks the validation standards required for autonomous vehicle certification in most jurisdictions. The system operates under Tesla's proprietary testing regime without independent third-party validation. No peer-reviewed safety studies confirm the system meets established safety benchmarks for Level 4 or Level 5 autonomy as defined by the Society of Automotive Engineers.
Tesla markets FSD as a full self-driving capability despite regulatory classification placing it at Level 2 autonomy, requiring active driver supervision. The discrepancy between marketing claims and actual system capabilities creates public misunderstanding about the technology's readiness.
The doubts from insiders carry weight because they possess technical knowledge of the system's architecture and training data. Data labelers understand the quality of inputs. Engineers understand algorithmic limitations. These voices contradict Tesla's public statements that FSD approaches human-level driving performance.
The National Highway Traffic Safety Administration opened multiple investigations into FSD-equipped vehicles involved in crashes. Tesla has not disclosed aggregate safety data comparing FSD-engaged accident rates to conventional vehicles. Without transparent, independent safety verification, claims about FSD readiness remain unsubstantiated by publicly available evidence.
